TOEPC7106171FD FP605 DRIVE INSTALLATION & PRIMARY OPERATION
will help verify the condition of the safety circuit. Refer to the manual for the safety device for more information
about the Safety function.
You can use the MFDO function settings to switch the polarity of the Safety monitor output signal. Refer to
for setting instructions.
Keypad Display
If the two input channels are OFF (Open), the keypad will flash
STo [Safe Torque OFF]
.
If there is damage to the Safe disable circuit or the drive, the keypad will flash
SToF [Safe Torque OFF Hardware]
when one input channel is OFF (Open) and the other is ON (Close the circuit). When you use the Safe disable circuit
correctly, the keypad will not show
SToF
.
If there is damage to the drive, the keypad will show
SCF [Safety Circuit Fault]
when the drive detects a fault in the
Safe disable circuit. Refer to the chapter on Troubleshooting for more information.

Validating the Safe Disable Function
After you replace parts or do maintenance on the drive, first complete all necessary wiring to start the drive, then test
the Safe Disable input with these steps. 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
If one or more of 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
.

Seismic Standards
The Yaskawa drives in this manual are capable of structurally and operationally withstanding the seismic response
criteria as defined in the International Building Code (IBC), ASCE7, and California Department of Health Care
Access and Information (HCAI).
The models in this manual were tested in compliance with AC-156 to meet the IBC seismic certification as shown on
the certification labels.
Refer to the Technical Reference (SIEPC7106171F) for seismic installation instructions.
