Reference Of The Terminal Fm (Pulse Train Output) (Pr.55, Pr.56) - Mitsubishi Electric FR-E700EX Instruction Manual

4.13.3 Reference of the terminal FM (pulse train output) (Pr.55, Pr.56)

The pulse train output terminal FM is available for monitor output.
Set the reference of the signal output from terminal FM.

55 Speed monitoring reference

56 Current monitoring reference

The above parameters can be set when Pr.160 Extended function display selection = "0". (Refer to page 182)

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.

When a value exceeding 3000 r/min is set, the rotation speed will be limited at 3000 r/min.
Also, when an S-PM geared motor is used, the maximum setting value differs depending on the drive unit capacity. (0.2 to 2.2K: 12000 r/min, 3.7K: 8000
r/min)

The setting differs according to the drive unit capacity. (0.75K or lower: rated current of MM-GKR motor (Refer to page 307.), 1.5K or higher: rated current of
S-PM geared motor (Refer to page 310.))
(1) Speed monitoring reference (Pr.55)
 Set the full scale value when outputting the speed monitor from terminal FM.
 Set the speed to be indicated as the full scale value on the speed meter (1mA analog meter) connected between terminal
FM and SD.
 Set the 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 monitoring 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.)
