VARIABLE-FREQUENCY MOTOR CONTROLLER REQUIREMENTS (AMEND 0003)
PART 1 - GENERAL
1.01 DESCRIPTION
A. This specification is to cover a complete Variable Frequency Drive (VFD) consisting of a pulse width modulated (PWM) inverter designed for use with both asynchronous and permanent magnet motors.
B. The drive manufacturer shall supply the drive and all necessary options as specified. All drives installed on this project shall be from the same manufacturer and have a common user interface (control panel).
