12. Start-up of Gearless (Permanent Magnet) Motor.
The below procedure illustrates a method for commissioning the drive in a typical elevator application, it is assumed the drive has already
been mechanically installed.
12.1. Step 1- Wiring Connections.
It is assumed the drive is connected as per Section 8.3 Overall Wiring Diagram and default terminal functions.
12.2. Step 2- Pre-Power Checks.
Action/Checks
 Check that all safety circuits/safety chains are in the correct state, failure to do so could result in damage to the
equipment and possible injury or death.
 Check that the intended voltage source matches that of the drive voltage rating.
 Check that any unexpected movement in the motor will not result in damage to equipment / safety risk to persons.
Do Not Apply
Electrical Power
 Check that the elevator controller will not give a start signal to the drive when Electrical power is applied.
Yet!
 Ideally the Lift car should be balanced (i.e. with brakes off the lift car should not naturally move) and with enough
shaft headroom to prevent reaching end stops during initial test travels.
 Check Electrical Supply cables are connected to the Input power terminals of the drive.
 Check Motor Cables are connected to the drive U, V, W terminals (If cables have identification markers connect
correct phase sequence).
Check all necessary
 Check Brake resistor is connected to the "+DC" and "BR" terminals of the drive and that the resistance is higher than
electrical
the minimum allowable value and resistor is suitably protected from thermal overload.
connections.
 Check correct control connections are made between the Elevator control panel and the drive. (as detailed in Section
8.3 Overall Wiring Diagram and default terminal functions).
 Check encoder module has been installed and the correct connections are made between the drive and the Encoder.
12.3. Step 3- Apply Power.
 Apply rated voltage to the
drive.
 Check that the drive displays

Additional Information
If or is not shown or a red light is shown on the encoder
module refer to section 20 Troubleshooting.
If there is no green light shown on the encoder module :
o
Check encoder module is pushed fully home.
o
Check the encoder wiring is correct.
