3.4.2.3 Connection of the analog speed set value
Speed (X2-8)
Unipolar input for the manual speed set value specification. This
function can be selected with the plug bridge STB3 „set value
source„ (see chapter 0).
Input voltage: 0 ... +10 VDC
Input resistance: Ri = 100 k
Ω
Reference potential: GND
3.4.2.4 Signal output
(X2-1/2)
The signal output connects several functions
to each other and trips when a failure occurs.
The connection is clearly shown in the circuit
diagram.
Monitoring functions:
- Temperature monitoring via
Thermal circuit breaker in the motor
- internal stand-by signal monitors
a) the intermediary circuit voltage
(95V < UZK <420) and
b) the heat sink temperature < 80°C
- Optionally the function set value actual value
monitoring can be connected with plug bridge
STB2.
If the regulator is cut-off when the stand-by
signal is tripped, it must be connected
externally!
