Troubleshooting - YASKAWA CIMR-LC2A0018 Quick Start Manual

Power On
Before turning on the power supply
• Make sure all wires are connected properly. Also make sure motor phases are connected in the right sequence.
• Make sure that no screws, loose wire ends, or tools are left in the drive.
• If an encoder option card is used make sure the encoder is wired correctly and the power supply on the option card is
set according to the encoder specification.
After turning the power on, the drive mode display should appear and no fault or alarm should be displayed. In case of
any error refer to
Control Mode Selection
When the drive is first powered up, one of the four control modes must be selected to match the application. Note that
Closed Loop Vector modes require encoder feedback cards. The table below indicates possible control modes depending
on the motor type and shows the required encoder feedback card.

Permanent magnet motor with EnDat 2.1/01 or
EnDat 2.2/01 encoder

Motor Rotation Direction Setup
Depending on the elevator configuration it might be necessary to change the motor direction in order to have the elevator
traveling up when the Up command is given to the drive. Do the following to check the motor rotation direction.
• The drive puts out voltage in U-V-W phase sequence when an Up command is input. Check the motor rotation with
this phase sequence (for most motors clockwise seen from the shaft side).
• If the motor drives the elevator in up direction with a U-V-W sequence, make sure parameter b1-14 is set to 0 (default).
• If the motor drives the elevator in down direction with a U-V-W sequence, set parameter b1-14 is set to 1.
Note: Always perform motor rotation direction setup prior to setting the encoder rotation direction.
Encoder Setup
Encoder Resolution Setup
Set the encoder resolution (incremental signal in case of absolute encoders with Sin/Cos tracks) in parameter F1-01.
Encoder Rotation Direction Setup
Perform the following steps to make sure the encoder rotation direction is set up correctly in the drive.
If information about the signal sequence of the encoder are available
• Check the sequence of encoder phases A and B when the motor drives the elevator in up direction.
• If the encoder A phase leads phase B, make sure F1-05 is set to 0 (default).
• If the encoder B phase leads phase A, make sure F1-05 is set to 1.
If no information about the signal sequence of the encoder are available
• Turn the motor manually in elevator up direction while checking the value of monitor U1-05.
• If the value in U1-05 is positive, the set encoder direction is correct.
• If the value in U1-05 is negative, alter the setting of parameter F1-05.
Note: Always set the motor rotation direction prior to the encoder rotation direction. Refer to
page 19.
