■ Validating the Safe Disable Function
After you replace parts or do maintenance on the drive, complete all necessary wiring to start the
drive, then follow these steps to test the Safe Disable input. Keep a record of the test results.
1. When the two input channels are OFF (Open), make sure that the keypad flashes STo [Safe
Torque OFF], and make sure that the motor is not running.
2. Monitor the ON/OFF status of the input channels and make sure that MFDO set to the
EDM function operates as shown in Table 18.3.
If one or more of the these items are true, the ON/OFF status of the MFDO may not display
correctly on the keypad.
• Incorrect parameter settings.
• A problem with an external device.
• The external wiring has a short circuit or is disconnected.
• There is damage to the device.
Find the cause and repair the problem to correctly display the status.
3. Make sure that the EDM signal operates during usual operation as shown in Table 18.3.
