CALIBRATION
This function block contains motor-
specific parameters.
When CONFIGURE ENABLE = TRUE,
the operation of the Block Diagram is
suspended and all Operator Station LEDs
will flash.

ARMATURE V CAL.
20
0.9800 to 1.1000
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
21
0.00 to 100.00 %
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
23
0.9800 to 1.1000
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
10
-5.00 to 5.00 %
If the speed feedback is not zero when the drive 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.
