11 Appx. 2: D/A Output Specifications for Drive Unit
481 IB-1501229-F
11.3.2 Spindle Drive Unit Settings
Internal data output (Data No. -1 to 3, 50, 60, 127)
Set when outputting data other than in standard magnification (the magnification is 1). When "0" is set, the
magnification will be 1, which is the same as when "100" is set.
(Example 1) When SP125=1, SP127=50
Commanded motor rotation speed is output to D/A output channel 1 in increments of 2000r/min/V.
(Example 2) When SP126=2, SP128=200
The torque axis current command is output to D/A output channel 2 in increments of 50%/V.

SP127 DA1MPY D/A output ch1 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)

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.

Example of D/A output waveform: 3000r/min during acceleration and deceleration
《 Speed FB 》
《 Current FB 》
< When 3000r/min is displayed at the setting range of “1000r/min/V” >
When the speed waveform at 3000r/min is measured using a
high-speed waveform recorder with SP127 set to “100”, the data
exceeds the D/A output range (+5.0V for forward run and 0V for
reverse run) at 2500r/min, but it will be cleared immediately and then
the remaining data will be output. Even if the data exceeds the D/A
output range more than one time, it will be cleared and the remains
will be output.
