Calibration - Parker 590+ DRV Product Manual

CALIBRATION

This function block contains motor-specific parameters.
When CONFIGURE ENABLE = TRUE, the operation of the Block Diagram is suspended and all
Keypad LEDs will flash.
CALIBRATION
Parameter
ARMATURE V CAL.
Trim adjustment of the motor armature volts to give exactly 100% at the required actual voltage value (e.g. 460V etc.).
Note: - Primary voltage calibration is achieved by adjusting the NOM MOTOR VOLTS parameter (CONFIGURE DRIVE function block).
IR COMPENSATION
Compensation for motor IR drop to improve regulation when using armature voltage feedback as the speed feedback. This is also used in field
weakening applications to improve dynamic response and speed holding stability, refer to "Initial Start-up Routine" in Chapter 4, Item 16.
ANALOG TACH CAL
Trim adjustment of the motor speed to give exactly 100% at the required actual speed value (e.g. 1500 RPM etc). Note: Primary tacho calibration is
achieved by adjusting SW1 - 3 on the tacho calibration board.
ZERO SPD. OFFSET
If the speed feedback is not zero when the motor is stationary (possibly due to hardware offsets etc.) the setting of this parameter to the value of the
offset will result in a zero reading from the speed feedback.
ARMATURE I (A9)
Selects operation of the current meter output (terminal A9), either bipolar or unipolar.
FIELD I CAL.
Trim adjustment of the motor field current to give exactly 100% at the required actual current value (e.g. 1.5A etc.). Note:- Primary field calibration
is achieved by adjusting the FIELD CURRENT parameter (CONFIGURE DRIVE function block).
