MD 1236* defines the recovery time for the compensation setpoint pulse when operation is
without its adaptation. MD 1236* applies to neural and conventional quadrant error
compensation. If the adaptation of the recovery time constant (neural QEC only) is selected
(MD 1812*, bit 2 = 1), MD 1236* defines the filter time constant in the middle of the working
range, MD 1364* defines the value for acceleration 0.
