The CIMR-AU4A0038FAA is a three-phase 400 Volt AC Drive. There are two modes on this AC drive – Programming Mode and Drive Mode. In Drive Mode, the user can operate the motor and observe U monitor parameters. Parameter settings cannot be changed or edited while in Drive Mode. In Programming Mode, the user can edit and verify parameter settings and perform Auto-Tuning. When the drive is in Programming Mode, it will not accept a Run command unless b1-08 is set to 1. If b1-08 is set to 0, the drive will only accept a Run command in Drive Mode. After editing the parameters, the user must exit the Programming Mode and enter Drive Mode before operating the motor.

Local mode is when the drive is set to accept the Run command from the digital operator RUN key. Remote mode is when the drive can be set to accept the Run command from an external device, such as input terminals or serial communications. Switch the operation between Local and Remote using the LO/RE key on the digital operator or via a digital input. After selecting local, the LO/RE light will remain lit. The CIMR-AU4A0038FAA will not allow the user to switch between Local and Remote during run.

Several Application Presets are available to facilitate setting up the drive for commonly used applications. Selecting one of these presets automatically assigns functions to the input and output terminals and sets a predefined number of parameters to values appropriate for the selected application. An Application Preset can either be selected from the Application Selection menu in the Setup Group or in parameter A1-06. The default parameter setting is 0, which disables the presets. The following setting ranges are listed below:
– 0: Disabled
– 1: Water supply pump
– 2: Conveyor
– 3: Exhaust fan
– 4: HVAC
– 5: Compressor
