Example: Analog reference value input with switching
A drive is to be driven with an analog reference value
a)
0 to + 10 V
b)
- 10 V to + 10 V
Using a switch the drive will be ramp controlled to 0 rpm or to a different speed.
What parameters should be set?
a) 0 to + 10 V:
Result:
b) - 10 V ... + 10 V:
Result:
