8. Parameter Description
Zero Point Hysteresis REF 1
Function Output A1
Amplification Output A1
Calculation Example:
E 34
A zero point hysteresis of the analog reference input REF1 is adjusted with this
parameter. Voltage fluctuations and ripple voltages around the zero point of the
setpoint value do not cause any drifting of the motor.
! Only when CP.7 or CP.8 > 0,00 s !

Example: If CP.17 is adjusted to 5 % then the drive
starts only at a setpoint value of +/- 0,5 V.
This parameter defines which varia-
ble is given out at analog output 1
(terminal X2.18).
Value Output variable
0 actual speed
1 apparent motor speed
2 actual torque
3 intermediate circuit voltage
4 speed reference variable
5 system deviation (speed control) -6000...+6000 U/min
6 setpoint torque
Parameter CP.19 defines the
amplifcation of the analog output
signal at output A1 (terminal X2.18).
