2.0 Changes from Standard Product
a. The energy savings function (B8-01 = 1) cannot be used in conjunction with the output voltage PID
controller in the V/Hz control method (A1-02 = 0) or an “OPE12 - Energy Save ON” fault will occur.
b. Parameters N9-10, N9-14, and N9-15 have been moved from the “Factory” access level to the “Advanced”
access level (A1-01) in the V/Hz control mode (A1-02 = 0) for easier access. The factory should be
consulted before adjusting these parameters.
3.0 Limitations
a. The output voltage PID controller is available only in the V/Hz control mode (A1-02 = 0).
b. The “P” group parameters cannot be used in the “User Access Level” (A1-03 = 1110).
c. This software is specifically designed for the applications described in section 1. This software should
not be used to control a motor.
