Issue Number: 4
This parameter needs to be set to zero for the freeze position to be captured. Once the
freeze has occurred this parameter is set to 1. To reacitvate it simply set it to zero.
For description see Pr
90.20
These 2 parameters store the position and turns of the feedback encoder at the time the
freeze input has been activated.
The drive regularly checks the position derived with the sine and cosine waveforms from
a SINCOS encoder via serial communications. Set this parameter to 1 to disable this.
When the Drive Encoder Position Check parameter is disabled (Pr
90.21=1) this
parameter can be used to communicate with the encoder connected via serial comms
with the drive.
