Parameters, Variables and Commands Ver. 0002 A - 49
SP12 FM (F1600) MotorRatedSpeed
Function: Synchronous: Rated Speed
Asynchronous: Base Speed. The constant power area is beyond this base speed
Valid values: Synchronous: Must be greater than SP10. otherwise, it issues 500 DV15=3
Asynchronous: Must be smaller than SP11.
SP20.# (F31.#) VoltageRpmVolt
Function: Parameters Voltage_rpm/Volt (SP20) and rpm_rpm/Volt (SP21), define the ratio
between the analog voltage and the motor speed. Corresponds to the CNC feedrate
concept of G00 Feed.
Valid values: 1000..10000 Millivolts
Default value: 9500 Millivolts
SP21.# (F81.#) RpmRpmVolt
Function: See SP20.
Valid values: 10..10000 (depends on the motor connected) rpm.
Default value: SP11 (MaximumMotorSpeed) rpm.
SP12 (RatedMotorSpeed) rpm.
SP30 *s (F1603) AnalogInputOffset1
SP31 *s (F1604) AnalogInputOffset2
Function: Compensation of the offset of analog inputs 1 and 2 respectively.
Valid values: -10000..10000 mV
Default value: 0 mV
SP40.# O (S125.#) VelocityThresholdNx
Function: Speed value below which logic mark “n
feedback
< n
x
” is activated. The logic mark is the
SV3 variable. It can be used to know when the speed exceeds a particular value. This
nomenclature n
x
corresponds to the one defined by Sercos. In the machine-tool
industry it is referred to as n
min
.
Example of how to use it:
If in a particular application, we would like to know when the motor exceeds 400 rpm.
We will set this parameter, SP40, with a value of 400. When the motor exceeds this
speed, its associated mark SV3 will be activated.
Valid values: 0..SP12 (depends on the motor connected) rpm.
Default value: 20 rpm.
SP41.# O (S157.#) VelocityWindow
Function: Speed window assigned to logic mark “n
feedback
= n
command
”.
The logic mark is variable SV4. This mark is used to find out when the actual motor speed
(n
feedback
) has reached the command value (n
command
) within the boundaries of this window
SP41
Valid values: 0..12% of parameter SP10 (VelocityLimit)
Default value: 20 rpm.
