Zero Return Speed; Zero Return Completed Flag; Change Of Zero Return Speed; Data Set Type Zero Return - Mitsubishi Electric FX2N-10PG User Manual

Model FX2N-10PG Pulse Output Block
8.3.5

Zero return speed

• Zero return speed (high speed)
Set Bias speed (BFM#2) ≤ Zero return speed (high speed) (BFM#6, #5) ≤ Maximum
(BFM#1, #0).
If Bias speed > Zero return speed (high speed), operation is executed at the bias speed.
• Zero return speed (creep)
Set Bias speed ≤ Zero return speed (creep) (BFM#7) ≤ Maximum speed (BFM#1, #0).
If Bias speed > Zero return speed (creep), operation is executed at the bias speed.
8.3.6

Zero return completed flag

When a series of operations are completed, CLR signal (20 to 30ms) is output. The value of
the zero point address is written into the current address, and the zero return completion
(BFM#28 b3) is turned ON.
The zero return completed flag is reset with the zero return command, data set type zero
return command or power shutdown.
8.3.7

Change of zero return speed

The zero return speed (high speed) and zero return speed (creep) can be changed at any
time.
However, a change can not be received when the speed change disable (BFM#26 b10) during
operation is ON.
8.3.8

Data set type zero return

In the data set type zero return mode, the work does not move, and the zero return process is
applied on the spot.
On equipment that does not use a dog switch, or a transfer line without a mechanical zero
point, the zero return process is done on the spot by turning ON the data set type zero return
command (BFM#26 b7) after moving the work to a desired position in the jog mode.
CLR signal (20 to 30ms) is output at the leading edge of the data set type zero return
command (BFM#26 b7), the value of the zero point address is written into the current address,
and the zero return completion (BFM#28 b3) is turned ON.
The zero return completed flag is reset with the zero return command, data set type zero
return command or the power shutdown.
