Local Control Operation
This is the simplest method of operating the
drive. 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.
The drive will display the Local screen. Refer to Chapter 5 and select Remote Control.
IMPORTANT:
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 Mode)
provides
less torque control at low speeds, but is ideal for controlling fans and pumps
in Sensorless Vector Mode
used for
maximum torque control at low speeds, for example, in operating a lift
