Description
Set [0000]:
modification to user parameters [PnXXX] and part
of auxiliary function parameters [FnXXX] permitted;
Set [0001]:
modification to user parameters [PnXXX] and part
of auxiliary function parameters [FnXXX]
prohibited.
Monitor if the number of sent and received pulse is
correct by setting this parameter. In Weihong
control system, the correct quantity of pulse sent by
control card is detected by pulse inspection in order
to determine whether there is electrical
interference.
Bit 0: Set 0, “CCW” is forward rotation (viewed from
the load end of screw ball); Set 1, the rotation
direction of the motor is reversed.
Bit 1: Set 1, position control mode (calculate pulse
instruction all the time).
Bit 0: Set 5, select the instruction input mode as
“pulse + direction”, negative logic.
Bit 3: Set 0, input differential signal into filter.
Bit 1: Set 0, Servo ON /S-ON, input from 40th pin;
Set 7, Servo ON all the time.
Bit 3: Set 8, positive rotation not used and signal
input (P-OT) prohibited.
Bit 0: Set 8, reverse rotation not used and signal
input (N-OT) prohibited.
Set it when servo motor with brakes.
Bit 2: Set 3, brake interlock signal “/BK” is output
from CN1-29, CN1-30 to control 24V relay for brake
Set it when servo motor with brakes
To avoid of CN1-29 and CN1-30 being used for
other function and leading to brake ineffective, “3”
is not allowed to appear in the 4 digits.
Set it when motor with brakes
Default setting is “0”, setting unit is 10ms.
