Product technial information:
Drive regulation is performed by a microprocessor on the Regulator board. Drive operation is adjusted by the parameters entered
through the keypad. The Regulator board accepts power circuit feedback signals and
an external speed reference signal, as well as data from an encoder that is attached to
the motor when set up for FVC regulation. The Regulator board provides:
• PWM gating signals to the IGBT power devices
Based on the output of the control loop, the regulator sends PWM gating signals
through the Current Feedback board to isolated drivers on the Gate Driver board.
These drivers switch the Insulated Gate Bi-polar Transistors (IGBTs), producing a
PWM waveform that corresponds to the speed (FVC regulation) or frequency (V/Hz
regulation) reference. The IGBTs can be switched at either a 2, 4, or 8 kHz carrier
frequency.
• Form A and B contacts for drive status indicators
The Form A and B contacts are under control of the user via programmable
parameters. A Form A or B transition can indicate drive status. The contacts are
rated for 5 amps resistive load at 250 VAC/ 30 VDC and are made available through
the terminal strip.
• Display data for a four-character display and fourteen indicator LEDs
For a description of the keypad/display, refer to section 2.8.6. For operational
instructions.
