Follow the procedure below to check the motor rotation. This procedure assumes that the

drive has been powered up for the ﬁrst time, and that none of the parameters have been

changed.

1. Use the t button to decrease the speed setpoint to 00.0 Hz. If the t button is

held down, the speed setpoint will decrease by tenths of Hz until the next whole

Hz is reached, and then it will decrease by one Hz increments. Otherwise, each

push of the t button will decrease the speed setpoint by a tenth of a Hz.

Once 00.0 Hz is reached, the display will toggle between “00.0” and “- - -”, which

indicates that the drive is in a STOP condition with a speed setpoint of 00.0 Hz.

2. Give the drive a START command. This can be done using one of several wiring

methods described in Section 11 - TCF CONTROL WIRING DIAGRAMS. Once

the START command is issued, the display will read “00.0”, indicating that the

drive is in a RUN condition with a speed setpoint of 00.0 Hz.

3. Use the s button to increase the speed setpoint until the motor starts to rotate. If

the s button is held down, the speed setpoint will increase by tenths of Hz until

the next whole Hz is reached, and then it will increase by one Hz increments.

Otherwise, each push of the button will increase the speed setpoint by a tenth of

a Hz.

4. If the motor is rotating in the wrong direction, give the drive a STOP command and

remove power from the drive. Wait three minutes for the bus capacitors to discharge,

and swap any two of the motor wires connected to T1, T2, and T3.

NOTE

The drive is phase insensitive with respect to incoming line voltage. This

means that the drive will operate with any phase sequence of the incoming

three phase voltage. Therefore, to change the motor rotation, the phases

must be swapped at the drive output terminals or at the motor.
