III.2.2 Output functions
III.2.2.1 Armature current monitor output
The output (IDC, pin 16b or terminal 7) delivers ±10 V against AGND for ± peak instrument
current. The measured value is nearly proportional to the motor torque which is delivered.
The output resistance is 2.2kW
This signal can also be used as a current setpoint signal for a second, 1:1 connected
(slave) transistor controller in a tandem drive.
For operating the transistor controller as a 1:1 current controller, see Chapter III.3.1.
III.2.2.2 System ready contact BTB
The operational readiness (BTB, pins 8bd or terminals 8,9) is signalled via a floating
relay contact (100V / 0.1A DC).
The contact is closed when the controller is ready for operation, the signal is not affected by
the Enable signal or the I

t limiting.
III.2.2.3 Measurement points
n
Armature current monitor (IDC), normalisation ±10V for ± peak instrument current,
output impedance 2.2 kW, reference point is Analog-GND.
n
Tacho monitor (VTA) , the voltage corresponds to the tacho voltage.
The reference point is Analog-GND.
