Frequently Asked Questions

What motor size is this 37A drive suitable for?
It is ideally matched for a 20 HP (15 kW) motor in Heavy-Duty applications, or an 18.5 kW motor in Normal Duty.

What is the RS-485 port used for?
It is used for serial communication, allowing you to connect the drive to a PLC, HMI, or supervisory system for control and monitoring using protocols like Modbus RTU.

Does it come with a keypad for programming?
This specific catalog number typically does not include a Human Interface Module (HIM). Programming is done via software connected to the communication port or with a separate HIM.

What is the purpose of the Common Mode (CM) Jumper?
The installed jumper connects an internal filter capacitor to the chassis ground. This helps reduce electromagnetic interference (EMI). Follow your plant's grounding scheme to determine if it should remain installed.

Can the analog input be used for speed control?
Yes. The analog input (e.g., 0-10V or 4-20mA) can be configured as a speed reference, allowing for precise speed control from an external potentiometer or controller signal.
