Motor Synchronization
If power up is successful, the door operator is ready to synchronize the motor.
1. Select LOCAL on the programming board.
2. Press Open/Close switch to provide a momentary OPEN or CLOSE command.
The motor will cog to synchronize the rotor. Time required for this operation varies, but should
be less than 2 seconds. When synchronization is complete, the door operator is ready to accept
commands.
IF… Motor does not cog and synchronize:
1. Confirm motor wires are connected correctly to main board at connector TB-2.
2. Confirm encoder wires are connected correctly to main board at connector TB-3.
3. Confirm programmer to main board connections (TB-9/J2 and TB-8/J1) are OK.
IF… Motor cogs indefinitely, drive shuts down (after two minutes), and red LED is ON:
1. Confirm ENCODER WIRES are connected correctly to main board at connector TB-3,
especially green wire on terminal 9.
2. Open rear cover of motor and check all connectors to make sure they are inserted cor-
rectly.
First Door Closing
If motor synchronization was successful, the next step is to CLOSE the doors. This is because
programming most board parameters can only be accessed after the drive detects FULL DOOR
CLOSE and the DCL signal is ACTIVE. Even though doors were closed by hand, IT IS ALWAYS
NECESSARY to give a close command until DCL is activated. When the first full door close
position is detected and DCL is generated, “Lr” will be displayed on the programmer board.
Parameters can now be accessed.
IF… Motor does not rotate properly, makes noise, or vibrates:
1. Confirm encoder wires are connected correctly to main board at connector TB-3.
2. Open rear cover of motor and check that all connectors are inserted correctly.
3. Confirm that the shielded wire of the encoder cable does not touch any metal part of the
enclosure or door operator.
4. If previous steps are OK, cycle power and repeat procedure.
IF… On the close command, doors move in open direction, brake, and drive resets:
1. Problems in start-up procedure were encountered and the drive reset. Procedure must
be repeated starting with Motor Synchronization.
2. If problems persist, cycle power and repeat entire procedure.
IF… Doors reach close position but the DCL signal is not generated, there is probably slip-
page somewhere in the mechanical transmission system and the motor is still turning while the
doors are stopped: (Please refer to “Establishing DCL” on page 17 also.)
1. Check belt tension. Tighten as necessary to prevent slippage. Grip-notch type belts may
be required.
