Step 1: Gather Required Information
Step 1: Gather Required Information
When you apply power to your drive for the first time, you need to enter specific information about your application. You
need to enter motor nameplate data and set up your I/O.
Step 1: Gather Required Information helps you to verify that you have the needed information prior to drive powerup.
Record Motor Nameplate Data
Record the motor nameplate data to be entered into the Motor Data parameters during powerup. You can also record data
for up to five drive/motor combinations. Use this table to record a descriptive name for each drive/motor combination and
their respective parameters.
Drive/Motor Name
(example, Main Exhaust Fan)
Drive/Motor 1: Drive/Motor 2: Drive/Motor 3: Drive/Motor 4: Drive/Motor 5:

(1) Use the Slip RPM rather than the Synchronous RPM.
Example: Use 1750 RPM rather than 1800 RPM for a 60 Hz motor.
Motor NP RPM

(3) To calculate: Number of poles = 120 x parameter 27 [Motor NP Hertz] / parameter 28 [Motor NP RPM]. Round the result to the nearest even whole number.
Example: 120 x 60 Hz / 1800 RPM = 4 poles
