report a braking overload fault (Er-bCE) by mistake or cause burnout of the braking
resistor. The regenerative braking overload protection time is proportional to these two
parameters. When Pc.54=0, the internal braking resistor is active.

By setting the numerator and denominator of the frequency division coefficient of
encoder pulse output, the phase A and phase B signals of the encoder can be
frequency divided by any integer or decimal fraction and then outputted through the
encoder’s pulse output signal terminals (OA+, OA-, OB+, OB-).
It should be noted that in the position control mode, if the encoder output signal of the
preceding stage servo motor is used as the position pulse command input of the
succeeding stage servo drive, i.e. as start/stop type master-slave follow-up, in order to
ensure high positioning accuracy of the succeeding stage servo drive, the frequency
division coefficient must be 1:1. Otherwise the accuracy of master-slave position
follow-up will be affected in this case.

This parameter is used to set the alarm threshold for the over-position fault (ER-oE). In
the position mode, when the number of retention pulses exceeds this setting, an
over-position fault alarm will be reported.
