7.2.6 Motor potentiometer
Motor potentiometer is used to control the reference with two digital inputs, one increasing the
reference and the other decreasing the reference. The reference change rate can be set by
parameter [Hz/s]. Motor potentiometer reference is available in I/O control only. It can be changed
only when the drive is in running state.

Ramp Rate
P2.2.11.1 Motor potentiometer ramp rate
ID331
“MotPot Ramp Rate”
Defines the rate of change of the motor potentiometer reference value in Hz/s. Normal
ramp times are still active and determine how fast the actual output frequency increases.
P2.2.11.2 Motor potentiometer reference reset ID367
“MotPotRef Reset”
0
“
No reset
”
Reference is kept past the stop state and stored to memory in case of a power down.
1
“Stop State”
Reference is set to zero when the drive is in stop state. This selection includes power
down situations.
2
“Power Down”
Reference is reset only in a power down situation.
3
“
StopReq; Fout
”
When the stop command is given and the drive is ramping down, the motor
potentiometer reference follows the actual output frequency. If new start command is
given while ramping down, the drive will stay at the frequency of the moment when
start command was given.
