See table below
Motor Rotation (C1)
Ensure the motor is wired to the drive with U to U, V to V and W to W
If the motor sheave will rotate in a
Clockwise
direction for the car to travel up, set Motor Rotation (C1) to
FORWARDS
If the motor sheave will rotate in an
Anti-clockwise
direction for the car to travel up, set Motor Rotation (C1) to
REVERSE
Encoder Pulses (A1)
The encoder pulses in the A1 menu should be picked from the table below:
PM Motor Frame Types Encoder Pulse (A1)
MX05/10
14395 PPR
MX05/16
14452 PPR
MX06/05
17067 PPR

MX10/15
19680 PPR

26050 PPR
MX20
12950 PPR (75mm Rider Wheel)
These values are simply a starting point. The final encoder PPR value will be entered once the motor can be run
at full speed as detailed in step 5.
If the motor does not conform to any of the types listed above, the PPR can be calculated using the diameter of
the sheave where the encoder rider wheel is running (This may differ from the sheave diameter on the motor
dataplate), and the diameter of the rider wheel supplied (37mm or 75mm).
