4 Setting up the drive
Set up the drive by adjusting potentiometers and replacing specific capacitors and fixed
resistors. These components are fitted to socket SK1. If a drive is replaced, the socket
can be transferred to the replacement drive in order to keep the settings.
4.1 Adjusting the potentiometers
Five potentiometers are labelled as follows:
RAMP
DERIVATIVE
PROPORTIONAL
ZERO OFFSET
MAX SPEED
Figure 4-1 Locations of the potentiometers on the drive
RAMP potentiometer
Adjust the potentiometer to increase or decrease the time from 0 second to 2 seconds
for the motor to reach maximum speed (with a 10V speed reference signal). To disable
ramps set the potentiometer at the fully anti-clockwise position.
DERIVATIVE potentiometer
Turn the potentiometer clockwise to reduce the amount of overshoot in the system
response by increasing the derivative gain of the PID amplifier.
PROPORTIONAL potentiometer
Turn the potentiometer clockwise to increase the proportional gain of the PID amplifier.
ZERO REF potentiometer
Adjust this potentiometer to cancel any offset in the external speed reference signal.
MAX SPEED potentiometer
Turn the potentiometer anti-clockwise to reduce the maximum motor speed to 50%.
Turn the potentiometer clockwise to increase the maximum motor speed to 120%.
