3) Select the PM default motor for the Motor ID (A5) parameter.
Enter / verify the following from the motor’s nameplate:

Motor HP or KW rating (RATED MTR POWER(A5))

Motor Voltage (RATED MTR VOLTS(A5))

Rated Motor current (RATED MOTOR CURR(A5))

Number of Motor Poles (MOTOR POLES(A5))

Rated Motor Speed at full load in RPM (RATED MTR SPEED(A5))
NOTE: Some motors do not quote the number of motor poles
however this can be simply calculated using this formula:
NOTE: Motor Frequency is not directly entered in the drive however useful to note to make the
above calculation if required.
In some instances the data on the motor data plate may not be 100% accurate (if the machine isn’t
‘made to order’ they may quote the motors maximum values as opposed to what is required for your
installation)
– if this is the case the ‘calculated’ motor data that matches your installation will have to be
obtained from the motor manufacturer and entered in the drive. This ‘Calculated’ data may have been
used to select the drive and the information on the data plate may be beyond the rating of the drive. It
is also important to verify and adjust the CONTRACT MOTOR SPEED parameter in the A1 Menu of
the drive at this stage.
4) Enter / verify the following encoder informations

Encoder Pulses (A1) should be set to encoder pulses on the encoder nameplate.

Serial Cnts/Rev (A1) should be set to serial counts on encoder

Encoder Select (C1) should be set according to the type of encoder that is being used.
Hoistway Parameter Set-up
5) Enter / verify the hoistway parameters:

CONTRACT CAR SPD (A1) parameter should be the elevator contract speed in ft/min.

CONTRACT MTR SPD (A1) parameter should be set to a RPM that will make the elevator
travel at desired car speed (measured with hand tachometer).
NOTE:
The above two parameters are utilized by the drive for many purposes regarding speed
control of the lift, therefore its important these are set correctly.
Encoder Alignment
6) There are mu
ltiple ways to gather the encoder angle alignment, some motor manufacturers ‘pre
set’ this to a default value to prevent any need for a motor alignment – if you have this information
you can enter it in the drive, if you do not know this skip to option 2
OPTION 1
– Predetermined Encoder angle offset

Clear any active faults in the drive in the F1 menu (and verify they have cleared)
