FOR MACHINE MANUFACTURERS

In order to comply with "ISO 13849-1" required in the region, the following is described.
Only the information that must be included in the owner's manual is described here. Therefore, some of the information required
to assemble the DC Power Unit into the equipment is included, and not all the information is provided.
For your information on DC Power Unit attachment
DC Power Unit safety functions include a function*
START/STOP switch and a function*
switch.
The torque to the motor is turned off within 500 ms after the stop signal is input from the START/STOP switch or a malfunction is
detected at the START/STOP switch.
*1 This function certainly stops the motor by a stop signal sent from the START/STOP switch
*2 This function prevents the motor from starting unintentionally
When you use the safety function, always conduct an equipment risk assessment and make sure that the safety function shown
below meets PL required for the equipment.

START/STOP switch monitoring system
• Prevent the motor from starting unintentionally
• Prevent the motor from being unstoppable
Explanation of terminology
Cat.
Classification of the safety-related parts of a control system in respect of their resistance to faults and their subsequent
behaviour in the fault condition, and which is achieved by the structural arrangement of the parts, fault detection and/or by
their reliability
DC avg
Measure of the effectiveness of diagnostics, which may be determined as the ratio between the failure rate of detected
dangerous failures and the failure rate of total dangerous failures
PL
For the purposes of this part of ISO 13849, the ability of safety-related parts to perform a safety function is expressed through
the determination of the performance level.
