Parameter
Description
*22
Motor[x].I2tTrip
Specify the allowable time for the rated short-time current value of
each motor and the servo amplifier. This is calculated based on the
following formula. The allowable time is 2 seconds based on the
specifications of the CDHD-0032APB0.
I2tTrip = (MaxDac
2
+ IdCmd
2
- I2tSet
2
) × Allowable time (s)
*23
Gate3[0].Chan[x].PwmDeadTime Specify 800 nanoseconds as the dead time of the PWM signal. The
dead time is calculated by the following formula.
DeadTime = 0.0533 μs × Gate3[0].Chan[x].PwmDeadTime
Set this value according to the specifications of the servo amplifier.
*24
Gate3[0].Chan[x].PwmFreqMult
Set the PWM output frequency to 15 kHz. The PWM output frequen-
cy is calculated by the following formula.
f
PWM
=
PwmFr 1
2
× Phase frequency
Set the PWM frequency to 40 kHz or less according to the maximum
input frequency of the servo amplifier.
*25
Gate3[0].Chan[x].PackOutData
Enable the compression format to realize a highly efficient algorithm
that completes writing to the output register for the U, V, or W phase
in two times.
If you use the CK3W-AX2323N, do not change this value.
*26
Gate3[0].AdcAmpStrobe
Specify the ADC strobe word (control command sent from the Con-
troller to the servo amplifier according to the Direct PWM standards).
Change this value according to the specifications of the servo ampli-
fier.
*27
Gate3[0].AdcAmpHeaderBits
Specify the number of header bits included in feedback current value
data. Change this value according to the specifications of the servo
amplifier.
*28
Gate3[0].AdcAmpClockDiv
Specify the clock signal frequency of the AD converter that reads
current data in the servo amplifier.
*29
Gate3[0].Chan[x].PackInData
Enable the compression format to realize a highly efficient algorithm
that completes reading from the input register for the U, V, or W
phase in two times.
If you use the CK3W-AX2323N, do not change this value.
*30
Gate3[0].Chan[x].AtanEna
Enable this if you use a sinusoidal encoder. If you use a pulse en-
coder or serial encoder, set it to 0.
*31
Gate3[0].Chan[x].EncCtrl
Set the decoding method of the encoder. In this manual, quadruple
AB-phase CW decoding is set.
*32
Motor[x].PosSf, Motor[x].Pos2Sf
Specify the conversion factor between the feedback value calculated
by the Axis Interface Unit and the command position.
This is set to 0.020/16384 since the pulse count per cycle is 16834
when a sinusoidal encoder is used and one cycle is 0.020 mm for the
sinusoidal encoder.
