Application example
For positioning a spindle feeding unit is driven via a gearbox. Instead of the standard resolver an
incremental encoder is used 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).
