Parameter Descriptions
ARMATURE V CAL
Range: 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 VA calibration values using SW7.
IR COMPENSATION
Range: 0.00 to 100.00 %
Compensation for motor IR drop to improve regulation when using armature voltage feedback as
the speed feedback.
ENCODER RPM
Range: 0 to 6000 RPM
Motor top speed setting when using encoder feedback.
ENCODER LINES
Range: 10 to 5000
The 5901 Microtach has 1000 lines per revolution as standard. Proprietary encoders of other
specifications can be normalised by setting this parameter as appropriate.
ANALOG TACH CAL
Range: 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
Range: -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.
ARMATURE I (A9)
Range: UNIPOLAR/BIPOLAR
Selects operation of the current meter output (terminal A9), either bipolar or unipolar.
SPDFBK ALM LEVEL
Range: 0.0 to 100.0 %
The speed feedback alarm compares speed feedback to armature voltage. The alarm level is the
threshold which the difference between the two signals should exceed for the alarm to activate.
