3.3.5. CN1 DI signals
There are 36 digital input functions could be assigned to the particular DI pin by the modification of
PD02 to PD09, PD21 to PD24. The value from 0x01 to 0x24 is defined as the function described below.
Functions/Applications description
Power on the drive and make SON-SG short-circuit to ready (the
shaft is locked). Make SON-SG open-circuit to release (the shaft
is rotatable). A virtual “Servo ON” could be achieved by the PD01
set as □□□1.(Normal ON)
A short-circuit duration over 50mS on RES-SG would recover
from an abnormal alarm status. Some abnormal cases would not
be recovered(refer to section 11.1). Set the PD20 as □□□1，
the function of reset would not work.
A short-circuit on PC-SG would switch the proportion-integral
controller to the proportion controller（speed control）. When
motor in static, it outputs torque to resist the external disturbance
which even only 1 pulse revolution. Once the position is done, to
prevent from unnecessary jitter of motor shaft, please switch to
the proportion controller.
Open TL-SG to make inner torque limit 1 valid(PA05), or turn
TL-SG on to make analog torque limit(TLA) valid.
For details, refer to section 6.3.4.
Inner torque limit
option
Turn TL1-SG on to make inner torque limit 2 valid(PC25). For
details, refer to section 6.3.4.
