0x2C12:001 SM low speed range: Acceleraon current
5 ... [70] ... 400 %
•
From version 02.00
R.m.s. current value for acceleraon processes in the lower velocity
range.
•
100 % ≡ Motor rated current (0x6075 (P323.00))
•
In the lower speed range and during the acceleraon phase, the cur-
rent setpoints of 0x2C12:001 and 0x2C12:002 are added and injected
to the motor.
0x2C12:002 SM low speed range: Standsll current
5 ... [30] ... 400 %
•
From version 02.00
R.m.s. current value for processes without acceleraon (for instance
standsll or constant setpoint speed) in the lower velocity range.
•
100 % ≡ Motor rated current (0x6075 (P323.00))
•
In the lower speed range and during the acceleraon phase, the cur-
rent setpoints of 0x2C12:001 and 0x2C12:002 are added and injected
to the motor.
Note!
At the "100 %" seng, a motor current ows at a standsll and at con-
stant speed. The eecve value of this motor current is greater than the
rated motor current by a factor of sqrt(2) at standsll. The reason for
this is that a DC current is injected into the synchronous motor at a
standsll. The correct rated motor current ows when the motor turns.
