Table 5- 38 The most important speed encoder parameters

Parameter Description

P0003 = 2 Extended access

P0400 = … Selecting the encoder type

• 0: Encoder signal is not evaluated

• 2: Encoder with pulse tracks A and B without zero pulse

• 12: Encoder with pulse tracks A, B and zero pulse

P0408 = … Number of encoder pulses per revolution

P0410 = … Reversing the internal sense of rotation

• 0: The encoder signal is not influenced

• 1: The encoder signal is inverted

P0491 = … Loss of speed response (response when the speed signal is lost)

• 0: Motor is shut down with fault message F0090

• 1: Alarm and switch to SLVC, if in SVC

P0492 = … Permissible speed difference to monitor the encoder signal (F0090)

P0494 = … Delay time of the loss of speed (delayed response when the speed signal is lost)

P1300 = 21

P1300 = 23

Control type:

21: Vector control with speed encoder

23: Torque-vector control with speed encoder
