1.9.8
K-VOUT/VEL-ERR
2
Proportionality constant of the motor speed error,
expressed in rpm per V. It defines how many rpm of
the speed error correspond to
1 volt
of the output
voltage added to an offset value. This parameter is
used when the analogue output is set to provide the
speed error reference ERR-VEL.
1.9.9
K-VOUT/POS-ERR
2
Proportionality constant of the motor position error,
expressed in Degrees per V. It defines how many
Degrees of position error correspond to
1 volt
of the
output voltage added to an offset value. This
parameter is used when the analogue output is set to
provide the position error reference ERR-POS.
The following parameters represent the proportionality constants between the analog output current and the selected
reference value (Grif), according to the following formula:
where,
Iout = analogue output current;
GRif = reference value (IQ, VEL and ABS-VEL, ERR-VEL, ERR-POS);
[K-IOUT/
GRif ] = proportionality constant;
[OFFSET[mA]] = offset value added to the analog output.
The setting of these constants, as well as of the offset value, allows defining the analog output dynamics and
consequently the full scale value:
1.9.10
K-IOUT/IQ
2
Proportionality constant of the IQ current, expressed
in A per mA. It defines how many Ampere of the IQ
current correspond to
5 mA
of the output current
added to an offset value. This parameter is used
when the analogue output is set to provide the
reference of the IQ current.
1.9.11
K-IOUT/VEL
2
Proportionality constant of the motor speed,
expressed in rpm per mA. It defines how many rpm
of the motor correspond to
5 mA
of the output
current added to an offset value. This parameter is
used when the analogue output is set to provide the
current speed reference of the motor (VEL and ABS-
VEL).
1.9.12
K-IOUT/VEL-ERR
2
Proportionality constant of the motor speed error,
expressed in rpm per mA. It defines how many rpm
of the motor correspond to
5 mA
of the output
current added to an offset value. This parameter is
used when the analogue output is set to provide the
motor speed error reference ERR-VEL.
1.9.13
K-IOUT/POS-ERR
2
Proportionality constant of the motor position error,
expressed in Degrees per mA. It defines how many
Degrees of motor position error correspond to
5 mA
