MDS-D2/DH2 Series Instruction Manual
4.3 Setting the Initial Parameters for the Spindle Drive Unit
【#13127】 SP127 DA1MPY D/A output ch1 output scale / Initial DC excitation time
Set the output scale in increments of 1/100.
When "0" is set, the scale is the same as when "100" is set.
When the DC excitation is running:
Use in the DC excitation function.
DC excitation: Set the initial excitation time when SP225/bit4=1.
When "0" is set, the state will be the same as when "10000" is set.
---Setting range---
-32768 to 32767 (1/100-fold)
【#13128】 SP128 DA2MPY D/A output ch2 output scale
Set the output scale in increments of 1/100.
When "0" is set, the scale is the same as when "100" is set.
---Setting range---
-32768 to 32767 (1/100-fold)
【#13129(PR)-13141(PR)】 SP129 - SP141
Set the unique constants for the spindle motor. (High-speed coil)
The setting value is determined by the motor's mechanical and electrical characteristics and
specifications, so normally set the value given in the spindle parameter list.
【#13142(PR)】 SP142
Set the unique constants for the spindle motor. (High-speed coil)
The setting value is determined by the motor's mechanical and electrical characteristics and
specifications, so normally set the value given in the spindle parameter list.
For IPM spindle motor
This parameter is used in initial magnetic pole detection of IPM spindle motor.
(1) Pulse application time: Set it in [μs] unit.(0 < application time < 350)
(2) Pulse application coil: To select a low-speed coil, add 1000 to the pulse application time.
(3) Polarity of estimated magnetic pole: When it is set to the reverse polarity, add "-" to the total of (1)
and (2).
E.g.: When performing 333μs pulse-applied magnetic pole estimation in a low-speed coil and
selecting the reverse polarity for the estimated polarity
SP142 = -(333+1000) = -1333
【#13143(PR)-13160(PR)】 SP143 - SP160
Set the unique constants for the spindle motor. (High-speed coil)
The setting value is determined by the motor's mechanical and electrical characteristics and
specifications, so normally set the value given in the spindle parameter list.
【#13161(PR)-13192(PR)】 SP161 - SP192
Set the unique constants for the spindle motor. (Low-speed coil)
The setting value is determined by the motor's mechanical and electrical characteristics and
specifications, so normally set the value given in the spindle parameter list.
【#13193】 SP193 LMR Change magnification for load meter standard output (High-speed
coil)
Set the standard output to be displayed as 100% in load meter using the short-time rated output
ratio.
To display the continuous rated output as 100%, set as follows.
Continuous rated output/Short-time rated output × 100
When "0" is set, normal display will be applied.
It is not available for MDS-DJ-SP Series.
