8-1-3 Setting the output scale
This is set when an output is to made with a unit other than the standard output unit.
(Example 1)
When SV061= 5, SV063 = 2560
The V-phase current value will be output with 4A/V unit to D/A output ch. 1.
(Example 2)
When SV063 = 11, SV064 = 128
The position droop will be output with a 8mm/V unit to the D/A output ch. 2.

Setting range
SV063 DA1MPY D/A output channel 1
output scale
–32768 to 32767
SV064 DA2MPY D/A output channel 2
output scale
When "0" is set, the output will be made with the standard output unit.
To change the output unit, set a value other than 0.
The scale is set with a 1/256 unit. When 256 is set, the unit will be the
same as the standard output unit.
8-1-4 Setting the offset amount
This is used when the zero level of the output voltage is to be finely adjusted. The output scale when
the data No. is 0 will be the offset amount. After setting the offset, set the data No. to a value other
than 0, and do not set it to 0 again. The offset value will be reset when the amplifier power is turned
OFF. (The value is not reset when the NC power is turned OFF.)
No.

SV063 DA1MPY D/A output channel 1
offset amount
The amount can be set with the output precision unit. Observe the output
value and set so that the output value is 0 V.
–10 to 10
8-1-5 Clamp function
This is used when the output value such as the position droop exceeds the output range and over
flows.
8-1-6 Filter function
A low path filter with a cutoff frequency of 140 Hz can be set.
