No.
1. Initial state
The inverter is in the "Ready" state (p0010 = 0).
•
The inverter signals neither faults nor alarms of the safety functions (r0945, r2122, r2132).
•
SDI is not active.
•
2. Switch on the motor (ON command).
Note: Select a direction of rotation of the motor, which should be prevented by the SDI function.
3. Check that the correct motor rotates in the expected direction.
4. Select the SDI direction to be checked while the motor is running.
Note: If you use SDI in both directions of rotation, perform this function test for both directions.
5. Check the following:
The motor brakes corresponding to the selected ramp time down to standstill. The inverter does
•
NOT switch off the motor, i.e. the motor is NOT torque-free.
The inverter signals:
•
"SDI is selected" (r9720.12 = 0 or r9720.13 = 0).
"SDI is active" (r9722.12 = 1 or r9722.13 = 1).
7. Deselect SDI.
8. Check the following:
The motor speed increases until the setpoint is reached.
•
The inverter signals neither faults nor alarms of the safety functions.
•
The inverter signals:
•
"SDI is deselected" (r9720.12 = 1 or r9720.13 = 1).
"SDI is not active" (r9722.12 = 0 or r9722.13 = 0).
