1-8 Introduction
Note: Since each inverter carries 1/2 of the motor load, in cases where
each inverter runs at 150% of the inverter rated load, the motor will run
at 150% of the motor rating if the motor and inverters have matched
ratings.
2 inverters x (150% load) x

= 150% of Motor Load.
• Output Frequency Range: 0 -150 Hz
• Efficiency: 97.5% at rated amps, nominal line volts
Performance Specifications -
• Speed Regulation to 0.001% of top speed.
• Torque Regulation to +/- 5 % of rated motor torque.
• Power Loss Ride Thru capability of 2 seconds (each standalone
inverter).
• Flying Start: Capable of starting into a spinning motor.
• Torque Linearity: 1%
• Overload Capability: 200% of motor or 150% of inverter rated
current whichever is less.
• Programmable Accel-Decel rates from 0 to 6553 seconds.
• Current Limit programmable from 200% of rated output current.
NOTE: M/S Current Loop Bandwidth and Velocity Loop Bandwidth
maximum values are 1/2 the values for a standalone FORCE drive.
