7.3.2.2 Pole Position Learn
The pole position learn must be done un-roped or with balanced load on the motor. DO
NOT DISABLE THE BRAKE! The benefit of the pole position learn is the drive will
determine the correct AB phasing of the encoder and learn the encoder position. The SPI
does not determine the AB phasing and will only learn the encoder position for the
encoder phasing selected in LE03 - Encoder Channel. During the learn the sheave will
turn slightly and there will be audible ping noises. To complete the pole position learn,
use the following instructions:
1. Set inspection speed to 0 (If US04 is set to Serial or Analog Speed the adjustment
will be on the controller, if US04 is Binary or Digital Speed the adjustment is in
Speed Profile parameter LS03 - Inspection Speed)
2. Go to parameter LL06 Encoder Pole Position Learn (HOME SCREEN > F3 PROG >
TUNE PARAMETERS > LL06 - POLE POSITION LEARN)
3. Change to Start.
4. Press ENTER on Start.
5. Give a command on inspection in either direction and learn will start, and the motor
will start to ping (10 times).
6. If a message appears notifying the AB phasing is incorrect and to stop commanding
inspection, release the inspection command.
7. The drive will internally change the AB phasing in LE03 and the screen will ask to
give the inspection command again.
8. Once the learn is complete the screen will display the average encoder position.
7.3.2.3 Encoder Synchronization
The encoder synchronization is an optional learn. The learn requires either the SPI or
Pole Position Learn to be done on a PM motor when un-roped or has a balanced load. A
speed value for inspection speed must also be given. DO NOT DISABLE THE BRAKE!
The encoder synchronization can determine the correct AB phasing of the encoder and
change the rotation of the motor if needed. The encoder synchronization will change the
LE03 value as needed. To complete an encoder synchronization, use the following steps:
1. Set inspection speed to a non-zero number (If US04 is set to serial or analog speed,
the adjustment will be on the controller. If US04 is binary or digital speed, the
adjustment is in speed profile parameter LS03 - Inspection Speed)
2. Go to parameter LL07 Encoder Synchronization (HOME SCREEN > F3 PROG >
TUNE PARAMETERS > LL07 ENCODER SYNCHRONIZATION).
3. Change to Start.
4. Press ENTER on Start; the operator screen will show instructions to move the motor
on inspection either up or down.
5. Follow the instructions as shown on screen (Move up when instructed to move up
and down when instructed to move down).
6. Once the learn is complete, the screen will display complete message.
