Mitsubishi FR-A800

Position control under vector control and PM sensorless vector control
246
PARAMETERS
Pulse monitor selection (Pr.430)
• Shows the various pulse conditions during operation as the number of pulses. Set "0" in Pr.52 Operation panel main
monitor selection to display the output frequency monitor.
• If any of "26 to 31" is set in Pr.52, Pr.774 to Pr.776, and Pr.992, the electronic gear operation setting for the pulse monitor
by the multifunction monitor can be changed. (Refer to page 359)
 Accumulated value of estimated feedback pulses when PM sensorless vector control is used
The pulse monitor of the operation panel (FR-DU08)
• The position command, current position and the status of droop pulses can be displayed on the operation panel.
• If displayed data has signs, minus signs appear for both upper and lower digits.
• If -99999999 or 99999999 is exceeded on the pulse monitor, the monitor value is reset to 0.
NOTE
• The pulse count starts at servo on.
• The accumulated number of pulses is cleared at base shutoff or when the CLR signal is turned ON.
• Changing the terminal assignment using Pr.178 to Pr.189 (input terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
