·ACC0:(Reference value 14)
ACC0 switches the acceleration/deceleration time.
The acceleration time and deceleration time of the servo motor follow the setting of P1.37 to 40 (acceleration
time, deceleration time). The acceleration time and deceleration time can be set separately.
The setting through ON/OFF of the ACC0 signal despite the direction of rotation, as shown in the table below
can be switched.

P1.38
ON
P1.39
P1.40
If no signal is assigned on the EI input terminals, it is always regarded as turning OFF.
·Position preset: (Reference value 16)
The command position and feedback position are preset (overwritten).
The command position and the feedback position are made the reference value of P2.19 (preset position) at
the rising edge. However, the deviation is subtracted from the feedback position.
The rising edge is the change point at which the EI input signal having been switched off to on.
As zero speed signal [NZERO] can be performed during ON, it is recommended to conduct position preset
while the servomotor is stopped. After position preset, homing is finished.
If no signal is assigned on the EI input terminals, it is always regarded as turning OFF.
·Servo response switch: (Reference value 17)
To switch the gain (response capability) of the servo system.
When P1.61 (Gain switch cause) is set at "3" (external switch: EI signal), the EI signal assigned to this function
switches the gain of the servo system.
The control gain parameters that are enabled with the servo response switch are listed in the table below.
Use the function to change the gain of the servo system between the going path and returning path in a
reciprocal motion or similar.
Servo response switch
Control gain
OFF
P1.55: Position loop gain 1
P1.56: Speed loop gain 1
P1.57: Speed loop integration time constant 1
P1.58: Feed forward gain 1
ON
P1.64: Position loop gain 2
P1.65: Speed loop gain 2
P1.66: Speed loop integration time constant 2
P1.67: Feed forward gain 2
If no signal is assigned on the EI input terminals, it is always regarded as turning OFF.
