13-52 GV6000 AC Drive User Manual
If the input is in current mode, 4 mA is the normal minimum usable input value. Any
value below 3.2 mA will be interpreted by the drive as a signal loss, and a value of 3.8
mA will be required on the input in order for the signal loss condition to end.
If the input is in unipolar voltage mode, 2V is the normal minimum usable input value.
Any value below 1.6 volts will be interpreted by the drive as a signal loss, and a value
of 1.9 volts will be required on the input in order for the signal loss condition to end.
No signal loss detection is possible while an input is in bipolar voltage mode. The
signal loss condition will never occur even if signal loss detection is enabled.
13.19.6 Trim
An analog input can be used to trim the active speed reference (Speed Reference
A/B). If analog is chosen as a trim input, two scale parameters are provide to scale the
trim reference. The trim is a +/- value which is summed with the current speed
reference.
