Keypad reference
If Keypad reference is selected, the drive sequencer is controlled directly by the keypad keys and the keypad reference parameter (Pr 1.17) is
selected. The sequencing bits, Pr 6.30 to Pr 6.34, have no effect and jog is disabled.
There is no forward/ reverse button on the drives keypad. If a forward/ reverse is required in keypad mode, see Pr 11.27 for how to set this up.
Note: For existing users of Commander SE:
On Commander SE, Pr 1.14 (Pr 21.03) used to correspond to Pr 05.
On Commander SK, Pr 11.27 corresponds to Pr 05.
If Pr 05 or Pr 11.27 is used in a desired system set-up and then Pr 1.14 (Pr 21.03) is then used to change this set-up, although some of these set-ups
for Pr 05 and Pr 1.14 (Pr 21.03) are the same, the displayed value showing the set-up of Pr 05 (AI.AV, AV. Pr etc.) will not change to the setting of Pr
1.14 (Pr 21.03)
Defines the acceleration ramp for motor 2
The acceleration ramp rate units can be change to s/10Hz or s/1000Hz, see Pr 2.39 on page 39 for details.
Defines the deceleration ramp for motor 2
The deceleration ramp rate units can be change to s/10Hz or s/1000Hz, see Pr 2.21 on page 38 for details.
The motor rated frequency and the motor rated voltage (Pr 21.09) are used to define the voltage to frequency characteristic applied to the drive (see
Pr 21.09). The motor rated frequency is also used in conjunction with the motor full load rpm to calculate the rated slip for slip compensation (see
Pr 21.08 on page 162).
