Fig. 9.9: Scaling of an analog channel
Example: Analog torque scaling
The standard setting for the drive is an input voltage range of 0 V to +10 V,
corresponding to 0 % to 100 %. With this setting, any value between -10 V and 0 V
corresponds to 0 %.
 Saythatyouwantaninputvoltagerangeof-10Vto+10V,inwhichcase-10
Vwouldcorrespondto0%ofthetorqueand+10Vto100%ofthetorque.

9.4.4Profilemodeandanaloginputs
Parameter P301[0] - CON_REF_Mode determines whether the reference values
are processed via the profile generator (setting “PG(0)”) or directly (setting “IP(1)”). If
direct input via IP mode is selected, only the input filters are active. The analog
values are scanned and filtered in the torque control cycle and then directly
transferred as references for the speed or torque control.
CAUTION! Your system/motor may be damaged if put into operation in
an uncontrolled or inadequate manner.
Failure to exercise caution or follow proper working
procedures may result in damage to your system/motor.

setpointhasbeenentered,astheconfiguredsetpoint
willbeimmediatelytransmittedtothemotorafterthe
