Up-To-Frequency Sensitivity (Pr. 41); Output Frequency Detection (Pr. 42, Pr. 43) - Mitsubishi Electric FR-E520 Instruction Manual

4.2.18 Up-to-frequency sensitivity (Pr. 41)

Pr. 41 "up-to-frequency sensitivity"
The ON range of the up-to-frequency signal (SU) output when the output frequency
reaches the running frequency can be adjusted between 0 and ±100% of the running
frequency.
This parameter can be used to ensure that the running frequency has been reached or
used as the operation start signal etc. for related equipment .

• Use any of Pr. 190 to Pr. 192 to allocate the terminal used for SU signal output.
Refer to page 163 for Pr. 190 to Pr. 192 (output terminal function selection).
Note: When terminal assignment is changed using Pr. 190 to Pr. 192, the other
functions may be affected. Check the functions of the corresponding terminals
before making settings.

4.2.19 Output frequency detection (Pr. 42, Pr. 43)

Pr. 42 "output frequency detection"
Pr. 43 "output frequency detection
for reverse rotation"
The output frequency detection signal (FU) is output when the output frequency reaches
or exceeds the setting. This function can be used for electromagnetic brake operation,
open signal etc.
• You can also set the detection of the frequency used exclusively for reverse rotation.
This function is effective for switching the timing of electromagnetic brake operation
between forward rotation (rise) and reverse rotation (fall) during vertical lift operation
etc.
