• The minimum input signal runs the drive at the maximum
reference in the reverse direction. Define the minimum
using parameter 1104.
• The maximum input signal runs the drive at maximum
reference in the forward direction. Define the maximum
using parameter 1105.
• Requires parameter 1003 = 3 (
Warning! Because the low end of the reference range
commands full reverse operation, do not use 0 V as the lower end of the reference range. Doing so means that if
the control signal is lost (which is a 0 V input) the result is full reverse operation. Instead, use the following set-up
so that loss of the analog input triggers a fault, stopping the drive:
• Set parameter 1301
• Set parameter 3021
• Set parameter 3001
