6153 3333 3189 4189
6333 3553
Standard setting: 0 0 X X X X 0 0
X: Depends on the amplifier model.
ESEC : Setting of detection edge of position coder one rotation signal
0: CCW=Rising edge CW=Falling edge (Normally set to ”0”)
1: CCW, CW=Rising edge
DS5–DS1:
Set the current dead band data.
PWM3K:
Sets a PWM carrier frequency in the low–speed range when speed
range switching is used.
The value to be set in this parameter varies with the motor model.
Usually, set 0.

Standard setting: 0 0 0 0 0 0 0 0
FFSMTH:
Presence of smoothing function on feedforward control
1: Without smoothing function
0: With smoothing function
Sets the presence of smoothing function on feedforward control of
servo mode (rigid tap, spindle positioning etc.).
RFCHK2:
Presence of 1 rotation signal error detection (AL-46) function for
position coder signal
0: 1 rotation signal error detection (AL-46) function not present
1: 1 rotation signal error detection (AL-46) function present
RFCHK3:
Presence of function for redetecting the 1 rotation signal for the
position coder signal each time spindle orientation/spindle
synchronization control/rigid tap zero return mode is entered.
0: The 1 rotation signal is not detected each time the operating mode
changes.
Once the 1 rotation signal has been detected, it is not detected
again until the power goes off.
1: The 1 rotation signal is detected each time the operating mode
changes.
