Explanation of the parameters
Parameters
P64x Analog outputs optional
Only with MCF/MCV/MCS40A, not MCH or MCx41A.
P640 / P643 Ana-
log output AO1 /
AO2 Depending on P642 Operating mode AO1 the signal range is 0 (4) ... 20 mA.
The following functions can be assigned to the analog outputs:
P641 Scaling AO1 Setting range: –10 ... 0 ... 1 ... 10
The slope of the characteristic curve for the analog outputs is defined.
Function
Scaling (at P641/P644 = 1)

NO FUNCTION Always 0 mA –
RAMP INPUT +/–3000 1/min 20 mA
Setpoint speed at the input of the internal ramp
generator
SET SPEED +/–3000 1/min 20 mA
Valid setpoint speed (output ramp generator or cor-
recting variable of master controller)
ACTUAL SPEED +/–3000 1/min 20 mA Actual speed AO1
ACTUAL FRE-
QUENCY

N
20 mA Apparent current
ACTIVE CURRENT +/–150 % I
N
20 mA
Active current, positive when torque is in positive
sense of rotation; negative when torque is in nega-
tive sense of rotation.
RELATIVE
TORQUE
+/–150 % I
N
20 mA
Active current that forms the torque; the value "0" is
always output in VFC operating modes.
