Functional Description
CG Drives & Automation, 01-5326-01r5
Acceleration Time Motor
Potentiometer [333]
It is possible to control the speed of the AC drive using the
motor potentiometer function. This function controls the
speed with separate up and down commands, over remote
signals. The MotPot function has separate ramps settings
which can be set in “Acc MotPot [333]” and “Dec MotPot
[334]”.
If the MotPot function is selected, this is the acceleration
time for the MotPot up command. The acceleration time is
defined as the time it takes for the motor potentiometer
value to increase from 0 rpm to nominal speed.
Communication information
Deceleration Time Motor
Potentiometer [334]
If the MotPot function is selected, this is the deceleration
time for the “MotPot” down command. The deceleration
time is defined as the time it takes for the motor
potentiometer value to decrease from nominal speed to 0
rpm.
Communication information
Acceleration Time to Minimum
Speed [335]
If minimum speed, [341]>0 rpm, is used in an application,
the AC drive uses separate ramp times below this level. With
“Acc<MinSpeed [335]” and “Dec<MinSpeed [336]” you can
set the required ramp times. Short times can be used to
prevent damage and excessive pump wear due too little
lubrication at lower speeds. Longer times can be used to fill
up a system smoothly and prevent water hammer due to
rapidly exhausting air from the pipe system.
If a Minimum speed is programmed, this parameter will be
used to set the the acceleration time parameter [335] for
speeds up to minimum speed at a run command. The ramp
time is defined as the time it takes for the motor to
accelerate from 0 rpm to nominal motor speed.
