Application example
For positioning a spindle feeding unit is driven via a gearbox. An incremental encoder is used instead
of the standard resolver as feedback system. The incremental encoder is mounted to the motor and
has a number of increments of 4096 pulses / rev. The gearbox has a ratio of i = 32 (n
motor
/n
spindle
).
The spindle has a lead of h = 10 mm. The entries are to be made in mm (1 mm = 1 unit).
