Operating the Drive

Local Control Operation

This is the simplest method of operating the
LOCAL
drive. The drive can only operate in V/F fluxing
control mode (VOLTS/Hz). Connect the keypad
to the drive and power-up the unit. The drive
will display the Local screen. If not, refer to
Chapter 5 and select Local Control.
Follow the instructions opposite to start and stop
the motor.
Reverse: Instead of setting a negative setpoint,
you can reverse the motor direction by pressing
STOP + , or START + .
To change the direction to forwards, (the normal
direction), press STOP +  or START + .
Note that the Setpoint parameter will not change
sign to indicate this change, however the
rotating indicator on the MMI will show the
direction.
We recommend that you use the STOP key commands if the motor is stopped, and the START
key commands if the motor is running. The keys should be pressed and released together.

Remote Control Operation

Connect the keypad to the drive and power-up the unit.
REMOTE
The drive will display the Local screen. Refer to Chapter 5 and select Remote Control.
Ensure that the speed potentiometer is set to zero.
Follow the instructions below to start and stop the motor using your control panel.
Reverse the motor's direction of rotation using the DIN2 connection (0V = forward, +24V =
reverse). Alternatively, swap two of the motor phases (WARNING: Disconnect the mains
supply first).
The installation of your drive is now complete:
The drive will operate as an open-loop drive. It is programmed to control an induction motor of
equivalent power, current, and voltage rating to the drive. Using the keypad (or other suitable
programming tool) the drive must now be set-up:
 as a simple Open-loop drive (V/F Fluxing Mode)
 in Sensorless Vector Fluxing mode

Single Wire Starting
provides less torque control at low speeds, but is ideal for controlling fans and pumps
used for maximum torque control at low speeds, for example, in operating a lift
