Appendix 1 Explanation of Parameters
【#2263】 SV063 DA1MPY D/A output ch1 output scale / Initial DC excitation time
Set output scale of the D/A output channel 1 in increment of 1/100.
When "0" is set, the magnification is the same as when "100" is set.
When the DC excitation is running (SV034/bit4=1):
Use this when the DC excitation is running (SV034/bit4=1) to adjust the initial magnetic pole
position (when measuring the magnetic pole shift amount) for linear motor and direct-drive motor.
Set the initial excitation time in DC excitation control.
Set 1000ms as standard.
When the magnetic pole shift amount measurement value is unsteady, adjust the value in
increments of 500ms.
Related parameters: SV061, SV062
---Setting range---
-32768 to 32767 (1/100-fold)
When the DC excitation is running (SV034/bit4=1): 0 to 10000 (ms)
【#2264】 SV064 DA2MPY D/A output ch2 output scale
Set output scale of the D/A output channel 2 in increment of 1/100.
When "0" is set, the magnification is the same as when "100" is set.
---Setting range---
-32768 to 32767 (1/100-fold)
【#2265】 SV065 TLC Machine end compensation gain
The shape of the machine end is compensated by compensating the spring effect from the machine
end to the motor end.
Set the machine end compensation gain. Measure the error amount by roundness measurement
and estimate the setting value by the following formula.
Compensation amount (μm) = Command speed F(mm/min)2 * SV065 / (Radius R(mm) * SV003 *
16,200,000)
Set to "0" when not using.
---Setting range---
-30000 to 30000 (Acceleration ratio 0.1%)
【#2266-2272】 SV066 - SV072
This parameter is set automatically by the NC system.
【#2273(PR)】 SV073 FEEDout Specified speed output speed
Set the specified speed.
Also set SV082/bit9,8 to output digital signal.
---Setting range---
0 to 32767 (r/min)
However, when SV033/bitD=1, the setting range is from 0 to 32767 (100mm/min).
(Only for MDS-D2/DH2 and MDS-DM2)
【#2274-2280】 SV074 - SV080
This parameter is set automatically by the NC system.
