Group 11: REFERENCE SELECT

This group defines:
• how the drive selects between command sources
• characteristics and sources for
Code Description
1101 KEYPAD REF SEL
Selects the reference controlled in local control mode.

• 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
