2.7 List of Possible Adjustments and Indicators

2.7.1 The LEDs

LED1 (green) Indicates readiness of the device; lights also when the amplifier is

not enabled.

LED2 (yellow) l

t- current limiting is active

LED3 (red) Fault (overcurrent, overvoltage, overtemperature).

LED4 (yellow) Ballast circuit operates (only for 120V devices).

2.7.2 The Potentiometers

Potentiometer 1 Signal Potentiometer scales the nominal speed input to match the

maximum velocity feedback used for adjusting the maximum motor

speed (10 to 100%).

Potentiometer 2 Pulse current limiting; range from 10 to 100% of the rated peak

current.

Potentiometer 3 Adjustment of the amplification of the speed controller.

Potentiometer 4 Offset adjustment of the speed controller.

Potentiometer 5 Continuous current limit; range from 0 to 100% of rated peak current.

2.7.3 The Test Points

MP0 Ground reference 0V

MP1 Nominal voltage Voltage at the differential -

nominal speed input (referred to ground)

MP2 Output of the speed controller (set value): 10V ≈ 15A (TBF60/5R)

≈ 25A (TBF60/10R)

≈ 18A (TBF120/7R)

MP3 Tachometer voltage: 10V ≈ 6000 rpm

MP4 Fault diagnosis 9V ±0.4V ≈ Overcurrent

8V ±0.4V ≈ Overvoltage

7V ±0.4V ≈ Overtemperature

MP5 Current monitor Phase V: 10V ≈ 15A (TBF60/5R)

≈ 25A (TBF60/10R)

≈ 18A (TBF120/7R)

MP6 Current monitor Phase U: 10V ≈ 15A (TBF60/5R)

≈ 25A (TBF60/10R)

≈ 18A (TBF120/7R)
