Mitsubishi Electronics FR-S500 instruction manual Speed display Pr, Setting

Explanation of functions (parameters)

2.3.17 Speed display (Pr. 37 )

You can change the output frequency indication or set frequency of the operation panel and parameter unit (FR-PU04) to the motor speed or machine speed.

Parameter	Name	Factory	Setting		Remarks
		Setting	Range
37	Speed display	0	0, 0.1 to 999	0:Output		Setting is enabled
				frequency		when Pr. 30 = "1".

<Setting>

•To display the machine speed, set in Pr. 37 the machine speed for 60Hz operation.

CAUTION

•The motor speed is converted from the output frequency and does not match the actual speed.

•When you want to change the monitor (PU main display) of the operation panel, refer to Pr. 52 "operation panel display data selection" and communication parameter n16 "PU main display screen data selection".

•Since the operation panel indication is 3 digits, make a setting so that the monitor value does not exceed "999". If the Pr. 1 value is higher than 60Hz and Pr. 1 value × Pr. 37 value > 60Hz × 999

(write error) occurs when Pr. 1 or Pr. 37 is written.

REMARKS

When the speed is set in Pr. 37 (Pr. 37 ≠ 0), the speed is monitored and displayed in the monitor/frequency setting mode.

At this time, setting can be made in the minimum setting (display) increments of 0.01r/min. Due to the limitations on the resolution of the set frequency, the indication in the second decimal place may differ from the setting.

CAUTION

Make sure that the running speed setting is correct.

Otherwise, the motor might run at extremely high speed, damaging the machine.
