Inching (MODE 1)

Definition
You use inching mode to control the drive directly in a particular direction using the DIR_M or
DIR_P control bits.
When you start MODE 1, the 1PosSSI/Analog moves the drive with the set voltage for
inching mode (from the control interface) in the specified direction (control bits DIR_M or
DIR_P).
You stop the drive by decelerating to 0 V by setting the control bits DIR_P = 0 and
DIR_M = 0.
You can change direction using deceleration or acceleration.
You can also activate inching on an unsynchronized axis (feedback bit SYNC = 0) or when
there is a pending encoder error (feedback bit ERR_ENCODER = 1) or without an encoder
connected.
