Dead band for position errors
Microstepping can be used to target 200 * 64 = 12800 positions. Since the encoder can only scan 1024 * 4 =
4096 positions, positions between two encoder scan points may not be picked up correctly, in which case the
terminal will control around this position The dead band for position errors is a tolerance range within which
the position is regarded as reached (Fig. "Dead band for position errors").

Setting the acceleration time
In order to pass through any resonances that may occur as quickly as possible, the ramps for the
acceleration time and the deceleration time should be as steep as possible.
