.
The above parameters allow their settings to be changed during operation in any operation mode even if "0" (initial value) is set in
Pr. 77 Parameter write
selection
.
The value left of the slash is for the 2.2K drive unit or lower. The one right of the slash is for the 3.7K drive unit.
If a value exceeding the upper speed limit of the motor is set, the actual operation will be limited at the maximum rotation speed. The setting range is for
the S-PM motor. The maximum setting value differs depending on the number of poles of the applied motor.
Refer to page
for the rated motor current.
(1) Speed monitor reference
(Pr. 55)
Set the full scale value when outputting the speed monitor from terminal FM.
Set the speed when the optional speed meter (1mA analog meter), which is connected to the terminal FM and SD,
shows 1500 r/min or 3000 r/min (shows full scale).
Set the rotation speed (set speed) at which the pulse speed of the FM output is 1440 pulses/s.
The pulse speed and rotation speed are proportional to each other. (The maximum pulse train output is 2400 pulses/s.)
(2) Current monitor reference
(Pr. 56)
Set the full scale value when outputting the current monitor from terminal FM.
Set the output current at which the pulse speed of the FM output is 1440 pulses/s.
The pulse speed and output current monitor value are proportional to each other. (The maximum pulse train output is
2400 pulses/s.)
