• 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
