52 Start-up
Action
Pre-requisites
The mechanical and electrical installation of the drive has been inspected and approved. See
checklist (page
49).
The insulation resistance of the assembly has been checked according to instructions. See
installation (page
27).
The supply unit of the drive system has been started up according to the instructions in its hardware
manual.
Checks/Settings with no voltage connected
Do the steps listed in
Electrical safety precautions (page
supply unit for more information.
Check the settings of breakers/switches in the auxiliary circuits. See the circuit diagrams delivered with
the drive.
Check that the auxiliary voltage selector [X59] on the front plate of the inverter modules is set according
to actual auxiliary voltage (230 or 115 V AC).
Disconnect any unfinished or uninspected auxiliary voltage (115/230 V AC) cables that lead from the
terminal blocks to the outside of the equipment.
Check that both channels of the Safe torque off circuit connected to the STO input of the inverter control
unit (A41) are closed. Refer to the wiring diagrams delivered with the drive.
With parallel-connected frame R8i inverter modules, check that the STO OUT output on the inverter
control unit (A41) is chained to the STO inputs of all inverter modules.
If the Safe torque off functionality is not used, check that the STO input on all inverter modules is correctly
wired to +24 V and ground.
Drives with Pt100 relays (option +(n)L506):
•Check the connections against the circuit diagrams of the delivery.
•Set the alarm and trip levels of the Pt100 relays.
Set the alarm and trip levels of the Pt100 relay as low as possible based on the operating temperature
and test results of the machine. The trip level can be set, for example, 10 °C higher than what the
temperature of the machine is at maximal load in the maximum environmental temperature.
We recommend to set the operating temperatures of the relay, typically for example, as follows:
•120...140 °C when only tripping is in use
•alarm 120...140 °C and trip 130...150 °C when both alarm and tripping are used.
Powering up the auxiliary circuit of the drive
Make sure that it is safe to connect voltage. Ensure that
•nobody is working on the drive or circuits that have been wired from outside into the drive cabinet
•the cover of the motor terminal box is in place.
Close the circuit breakers and/or fuse disconnectors supplying the auxiliary voltage circuits.
Close the cabinet doors.
Close the main breaker of the supply transformer.
Switch on the auxiliary voltage.
Setting up the inverter unit parameters, and performing the first start
Set up the inverter control program. See the appropriate start-up guide and/or firmware manual. There
is a separate start-up guide only for some control programs.
With inverter units consisting of frame R8i modules, check the setting of parameter 95.09 Switch fuse
controller.
Drives with an fieldbus adapter module (optional): Set the fieldbus parameters. Activate the appropriate
assistant (if present) in the control program, or see the user's manual of the fieldbus adapter module,
and the drive firmware manual. Check that the communication works between the drive and the PLC.
Drives with an encoder interface module (optional): Set the encoder parameters. Activate the appropriate
assistant (if present) in the control program, or see the user's manual of the encoder interface module,
and the drive firmware manual.
