10 = Cur rent freq uency, sup e rv i s e d by PI *,
11 = Torque current limit ation (limiting) , depends on parameter (P112), this value
corresponds to 100% of the setpoint value. Attainment of the set limiting value causes a
reduction of the output frequency at the limit of the torque current.
12 = Torqu e curr ent limit ation (switch- off ) , depends on parameter (P112), this value
corresponds to 100% of the setpoint value. The attainment of this set limiting value
causes switch-off with error code E12.3.
13 = Current limit (limiting) , depends on parameter (P536). This value corresponds to 100%
of the setpoint value. The attainment of the set limiting value causes a reduction of the
output voltage in order to limit the output current.
14 = Current limit (switch- off ) , depends on parameter (P536), this value corresponds to
100% of the setpoint value. The attainment of this set limiting value causes switch-off
with error code E12.4.
15 = Ramp time , is a typical setting value for the function of the potentiometers P1 or P2
(P400 [01] or [02]), which are integrated in the cover of the FI (Section 5.1.3).
Standardisation: T_Ramp time= 100Hz*U[V]/10V (U=voltage potentiometer (P1 or P2))
16 = Pre-tension Torque , function which enables a value for the anticipated torque
requirement to be entered in the controller (interference factor switching). This function
can be used to improve the load take-up of lift equipment with separate load detection.
17 = Multiplication , the setpoint is multiplied with the specified analog value. The analog
value adjusted to 100% then corresponds to a multiplication factor of 1.
18 = Curve control (Curve travel calculator) , via the external analog input (P400 [-03] or
P400 [-04]) or via the BUS (P546 [-01 .. -03]) the master receives the actual speed from
the slave. From its own speed, the slave speed and the guide speed, the master
calculates the actual setpoint speed, so that neither of the two drives travels faster than
the guide speed in the curve.
19 = Servo mode torque , in servo mode, the motor torque can be set or limited using this
function.
25 = Ratio gearing (Gearing transformation factor) , is a multiplier which takes into account
a variable transformation of the setpoint value. E.g.: Setting of the transformation
between the master and the slave by means of a potentiometer.
30 = Motor temperature : enables measurement of the motor temperature with a
KTY-84 - temperature sensor (Details in Section 5.3)
33 = Set point val ue torque p rocess controller : for the even distribution of torques to the
coupled drive units (e.g.: synchronised roller drive). This function is also possible with
the use of ISD control.
*) For further details of the PI and process controller, please refer to Section 9.2.
**) The limits of these values are formed by the parameters >minimum frequency auxiliary
setpoint values< (P410) and the parameter >maximum frequency auxiliary setpoint values<
(P411), whereby the limits defined by (P104) and (P105) cannot be undershot or overshot.
