Analog Input/Output Parameter Setting
(1)
Analog Speed Scale Setting
Analog speed scale [P2-17]: Set the analog speed command of 10 [V] in the unit of [RPM]. The
maximum value is the maximum motor speed.
Analog speed command offset [P2-18]: There are cases where a certain level of voltage remains on
the analog signal access circuit, even at the 0 speed command. In this case, you can compensate it
by setting the voltage as offset. The unit is [
㎷
].
Zero speed command clamp setting
(2)
Analog Torque Scale Setting
Analog torque command scale [P2-20]: Set the analog torque command of 10 [V] as a percentage
of the rated torque. The setting should be within the torque limit [P1-13] and [P-14] of system
parameter setting.
Torque command offset [P2-21]: There are cases in which a certain level of voltage remains on the
analog circuit, even at the 0 torque command, because of problems with the circuit. You can
compensate this by setting the voltage as offset. The unit is [
㎷
].
