Note
Deactivated functions in simulation mode
The following functions are deactivated in the simulation mode:
Motor data identification
Motor data identification, rotating without encoder
Pole position identification
restart is carried-out for V/f control and sensorless closed-loop vector control.
Note
Activating binector output r0863.1 in the simulation mode
In the simulation mode, binector output r0863.1 is set = 1. Therefore, before activating the
simulation mo
de, check as to whether additional devices are switched on using the signal. If
necessary, the corresponding BICO interconnection should be temporarily removed.
Simulation is activated using p1272 = 1; the following pre-requisites must be fulfilled:
● The drive unit must have been commissioned for the first time (default: Standard
induction motors).
● The DC link voltage must lie below 40 V (observe the tolerance of the DC link voltage
sensing).
Alarm A07825 (simulation mode activated) must be output during simulation operation.
p1272
Direction reversal
Description
The direction of rotation of the motor can be reversed using direction reversal via p1821
without having to change the motor rotating field by interchanging two phases on the motor
and inverting the encoder signals using p0410.
Reversal via p1821 can be detected from the motor direction of rotation. The speed setpoint
and actual value, torque setpoint and actual value remain unchanged, as does the relative
position change.
