Parameter
Specify which bits of the register in No. 14 you want to use for feed-
back values. Set this value according to the specifications of the AD
converter for reading current values that is installed in the servo am-
plifier.
Specify the start address of the register to which to write the com-
mand output of the Controller. Here, the U-phase
(Gate3[0].Chan[0].Pwm[0]) at the start of the register is specified
since the register of the CK3W-AX2323N for U-, V-, or W-phase out-
put is the output destination.
Specify the output volume during phase reference search. If phase
reference search is not completed, increase the value of this param-
eter since the output volume may be insufficient. Also, if an I2TFault
status error occurs during phase reference search, decrease the val-
ue since the output current has exceeded the rated value.
Specify the duration of time in phase reference search. If phase ref-
erence search is not completed, increase the value of this parameter.
Also, if an I2TFault status error occurs during phase reference
search, decrease the value since the output current has exceeded
the rated value.
Specify the coefficient of Direct PWM output. The full range is 16384.
This is normally set to less than 95% of the full range so that the duty
cycle of the PWM waveform does not reach 100%.
Set the parameter value according to the specifications of the servo
amplifier in use.
Specify the rated continuous current value of each motor and the
servo amplifier. This is calculated based on the following formula.
MaxDac =
Here, the rated continuous current of the servo amplifier is used
since it is smaller than that of the motors used for both the X and Y
axes.
CDHD-0032APB0: 9 A rms
INC-5716D0-0S: 9.88 A rms
INC-5723D0-0S: 14.82 A rms
Also, the full range of feedback current is 11.25 Arms based on the
specifications of the CDHD-0032APB0.
Specify the rated short-time current value of each motor and the ser-
vo amplifier. This is calculated based on the following formula.
I2tSet =
Here, the short-time rated current of the servo amplifier is used since
it is smaller than that of motors used for both the X and Y axes.
CDHD-0032APB0: 3 A rms
INC-5716D0-0S: 3.08 A rms
INC-5723D0-0S: 4.62 A rms
