4. Operation
4.1 Managing the keypad
The drive is configured and its operation monitored via the keypad and display
NAVIGATE:
Used to display real-time information,
to access and exit parameter edit mode and to store
parameter changes
UP:
Used to increase speed in real-time mode or to
increase parameter values in parameter edit mode
DOWN:
Used to decrease speed in real-time mode
or to decrease parameter values in parameter edit
mode
RESET / STOP:
Used to reset a tripped drive. When in Keypad mode (see
below and P1-12 in the parameter section) is used to Stop a running drive.
START:
When in keypad mode, used to Start a stopped drive or to reverse the
direction of rotation if bi-directional keypad mode is enabled (see P1-12 in the
parameter
section)
To change a parameter value
press and hold the NAVIGATE key for >1s whilst the
drive displays STOP. The display changes to P1-01, indicating parameter 01 in
parameter group 1. Press and release the NAVIGATE key to display the value of this
parameter. Change to the required value using the UP and DOWN keys. Press and
release the NAVIGATE key once more to store the change. Press and hold the
NAVIGATE key for >1s to return to real-time mode. The display shows STOP if the drive
is stopped or the real-time information (eg speed) if the drive is running.
To change parameter group,
ensure that extended menu access is enabled then
press NAVIGATE, simultaneously pressing and releasing the UP key until the required
parameter group is displayed.
To reset factory default parameters
, press UP, DOWN and STOP for >2s. The
display shows “P-dEF”. Press the STOP button to acknowledge and reset the drive.
4.2 Easy
startup
1.
Connect motor to drive, checking star/delta connection for the voltage rating
2.
Enter motor data from motor nameplate :
P1-07 = motor rated voltage
P1-08 = motor rated current
P1-09 = motor rated frequency
3.
Enable the drive. The drive automatically carries out a static Auto-tune
4.
Optidrive 3GV Only
- For high performance vector, set P1-14 = 101, P4-01 = 0,
then set P4-05 = motor nameplate power factor (cos
Φ
). Setting P4-02 = 1 then
starts the static Auto-tune.
To operate in terminal mode (default setting),
connect a switch between terminals 1
and 2 on the user terminal block. Connect a potentiometer (2k2 to 10k) between
terminals 5, 6 and 7 with the wiper connected to pin 6.
Close the switch to enable the drive. Adjust speed with the potentiometer.
To operate in keypad mode,
set P1-12 = 1 (uni-directional) or 2 (bi-directional). Place
a wire link or switch between terminals 1 and 2 on the user terminal block to enable the
drive. Now press START. The drive enables at 0Hz. Press the UP button to increase
speed. Press the STOP button to ramp to stop.
The desired target speed can be preset by pressing STOP whilst the drive is stopped.
When the START key is subsequently pressed, drive will then ramp to this speed.
