Short Description Adjustment of the speed of the external Encoder


VEXTRES is used if EXTPOS = 1 (position information of an external encoder for the position controller), and VMIX is < 1 (the speed of the external encoder is also used for the speed controller). It gives the gear factor to the drive.

VEXTRES changes the scaling of the speed of an external encoder.

For example:

1. Gearing factor 12 : 1, means 1 motor turn for 12 encoder turns, then VEXTRES = 12

2. Gearing factor 1 : 12, means 12 motor turn for 1 encoder turns, then VEXTRES = 0.083

VEXTRES can have up to 3 fractional digits.
