Action
Powering up the main circuit of the drive
Close the main switch-disconnector [Q1.1] or main breaker [Q1].
Note: Do not use excessive force. The main switch-disconnector (or main breaker) can only be closed
when
• the main input terminals [L1, L2, L3] are powered, and
• auxiliary voltage is switched on [Q21], and
Turn the operating switch (S21) to the ON (1) position to activate the run enable signal. Depending on
control source settings, this may also close the main contactor (if present). If a main contactor is present
and does not close, refer to the circuit diagrams delivered by the drive as well as the appropriate firmware
manuals.
On-load checks
Start the motor to perform the ID run.
Check that the cooling fans rotate freely in the right direction, and the air flows upwards.
Check that the motor starts. stops and follows the speed reference in the correct direction when controlled
with the control panel.
Check that the motor starts. stops and follows the speed reference in the correct direction when controlled
through the customer-specific I/O or fieldbus.
Drives in which the Safe torque off control circuit is in use: Test and validate the operation of the Safe
torque off function. See section
Start-up including acceptance test (page 209) .
Drives with an emergency stop circuit (oQ951, +Q952, +Q963, +Q964, +Q978, +Q979): Test
and validate the operation of the emergency-stop circuit. See the delivery specific circuit diagrams and
wiring, start-up and operating instructions of the option.
