Motion Safety

Increase Machine Uptime

Minimize operation intervention time

ISSUE

• In a machine operation intervention such as removing a crashed product, the machine is stopped, so there is no production.

SOLUTION

• You can pickup the product safely with Safely-Limited Speed function. The production line is running at limited speed but it is not stopped.
• Machine restarts smoothly from speed limit to normal speed.

Reduce changeover time

ISSUE

• In a coil change, the machine operator has to set the material in each roll with inching or jog function. It makes the change over complex and time consuming.

SOLUTION

• Machine operator can set the material in the roll with Safely-Limited Speed and introduce the film smoothly with Safe Direction function. It helps the operator to reduce the change over time and complexity

Avoid machine stops

ISSUE

• In a machine operation intervention, the stacker is stopped, so there is no production

SOLUTION

• When the operator is close, the stacker run slowly with Safely-Limited Speed without stopping.
• If the operator gets too close, then the Safe Brake Control function is activated to hold the stacker in a safer mode.

Zero startup rejects

ISSUE

• Disposal of product waste occurs. If the power to a motor is stopped following an emergency stop, film may be caught in the machine.

SOLUTION

• Even in the event of machine stoppage due to an emergency stop, disposal of product waste will not occur.
• Power is continuously supplied to a motor even during the emergency stop, therefore preventing film from getting caught in the machine.

Outline of Safety Functions

Details about Safety Functions

Function	Description
Safe torque off (STO)	The function is used to cut off a motor current and stop the motor.
Safe stop 1 (SS1)	This function is used to stop a motor by activating STO function at any timing after receiving a command from a safety controller.
Safes stop 2 (SS2)	This function is used to monitor a motor's stop by activating SOS function at any timing after receiving a command from a safety controller.
Safe operating stop (SOS)	This function is used to monitor that a motor stops at any positions. Both a position and velocity are monitored. Excessive limit value error occurs when the motor operates from a position where it stops.
Safely-limited speed (SLS)	This function is used to monitor a safety present motor velocity. When the safety present motor velocity exceeds the velocity limit for monitoring, excessive limit value error occurs.
Safely-limited position (SLP)	This function is used to monitor current positions. Excessive limit value error occurs when the positions surpass a range for monitoring.
Safe direction (SDI)	This function is used to monitor motor's rotating direction. Excessive limit value error occurs when a motor rotates toward the banned rotating direction.
Safe brake control (SBC)	This function is used to provide safety output for a holding brake. The function can be used with STO, SS1 functions and the brake operation.

Safety Servo Drives have two type STO functions. Use either or both functions according to configuration of safety devices.
• STO function by safety input signals
• STO function via EtherCAT communications
When you use just STO function by safety input signals, you do not need a setting related EtherCAT network.

Achievable safety levels for each safety function at maximum are shown as the below table:

Function	Achievable safety level	Function	Achievable safety level
STO	SIL3/PLe	SLS	SIL3/PLe *1
SS1	SIL3/PLe	SLP	SIL3/PLe *2
SS2	SIL3/PLe	SDI	SIL3/PLe *1
SOS	SIL3/PLe *1	SBC	SIL3/PLe *3

*1. Achievable safety level varies in a basic control for use.
*2. Achievable safety level varies in Safety Origin Position Determination Method or SOPT input devices for use.
*3. Achievable safety level varies in Brake structure.

Refer to the AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications and Safety Functionality User's Manual (Cat. No. I621) for details.

Configuration for Safety System

To make devices enter into safe state, a combined control among a safety controller, a standard controller and a Servo Drive is required.
Typical roles of each device are shown as below.

Device	Role
Safety Controller	• Monitor safety input and output. • Notify a standard controller of states of safety input and output. • Issue commands to activate and interrupt safety functions to a Servo Drive. • Issue commands to reset errors of safety functions to a Servo Drive.
Standard Controller	• Issue commands to turn Servo ON/OFF and reset errors to a Servo Drive. • Issue command to control a specified position, velocity and torque of a Servomotor to a Servo Drive.
Servo Drive	• Turn Servo ON/OFF and reset errors after receiving commands from a standard controller. • Control a Servomotor after receiving commands from a standard controller. • Activate and interrupt safety functions after receiving commands from a safety controller. • Reset errors of safety functions after receiving commands from a safety controller. • Stop a Servomotor when an error occurs.

A procedure for the control is described as follow:
1. A safety controller detects the following cases with a safety sensor and a safety switch.
   When workers entered exclusion zones
   When workers are about to touch hazardous sites of the device
   When workers come closely to the devices for the purpose of a check of devices/products, maintenance and supply of
   materials
2. A safety controller notifies a standard controller of the detected data.
3. A standard controller issues commands to decelerate and stop a Servomotor to a Servo Drive. At the same time, a safety
   controller issues commands to activate safety functions for use to a Servo Drive.
4. A Servo Drive receives and executes the commands from both controllers.

Thus, a safety controller and a standard controller must issue commands to a Servo Drive at an appropriate timing according to states of switches, sensors and devices, and then have the programs to issue the commands.
To secure the combined operation between a safety controller and a standard controller, design programs for each device with consideration of the following times. Without this consideration of the times mentioned earlier, when safety functions are activated, STO may be active and an excessive limit value error (Error display No.71.03) may occur.
   • Time until safety functions starts the activations
   It refers to “Time until a safety controller issues command to activate safety functions + Delay time of safety functions”.
   • Delay time of safety functions
   Time until STO becomes active or a Servo Drive starts monitoring after it receives commands of safety functions.
Refer to the AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications and Safety Functionality User's Manual (Cat. No. I621) for details.

*1. This is a typical value for when the Servomotor is used at a normal temperature (20°C, 65%) in combination with a
     Servo Drive.
*2. The rated values are the values with which continuous operation is possible at an ambient temperature of 40°C when
     the Servomotor is horizontally installed on a specified radiator plate.
*3. The momentary maximum torque is approximately 300% of the rated torque, except for some models.
*4. The momentary maximum torque is approximately 350% of the rated torque. Output at the momentary maximum
     torque shortens detection time of the overload protection function. Refer to Electronic Thermal Function in the AC
     Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications and Safety Functionality User's Manual
     (Cat. No. I621) for details.
*5. This value is for models without options.
*6. The allowable radial and thrust loads are the values determined for a limit of 20,000 hours at normal operating
     temperatures.
     The allowable radial loads are applied as shown in the following diagram.

* The value is the maximum allowable torque of the Decelerator. Take care so that this value is not exceeded.

Note: 1. The Decelerator inertia is the Servomotor shaft conversion value.
2. The protective structure rating of the Servomotor combined with the Decelerator is IP44.
(Excluding decelerator and servo motor connecting parts.)
3. The Allowable radial load column shows the values obtained at the center of the shaft (T/2).

R88M-1A[] / R88D-1SAN[]-ECT Specifications 68

4. The standard shaft type is a shaft with key and tap. (The key is temporarily assembled to the shaft.)
5. Take care so that the surface temperature of the Decelerator does not exceed 90°C.
