Pulse Output (
f1
/
f2
)
Outputs a preset number of pulses per Encoder rotation. Pulses are
output at a 1:1 ON/OFF ratio and pulse output can be started from a
specified angle.
Number of Output Pulses (
f1
)
Select the number of pulses per rotation from the following table.
Note:
Default settings are shown in reverse type.
The number of pulses is set using the F1 menu in the Function
Setting Mode.
Setting Display
Pulse Output Start Angle (
f2
)
The setting ranges are given in the following table.
Note: 1.
Default settings are shown in reverse type.
2.
The output accuracy is 2
°
maximum, so not all angles can
be set.
The starting angle for pulse outputs is set using the F2 menu in the
Function Setting Mode.

Speed Alarm Outputs (
f3
/
f4
)
Specific cam outputs can be used as Encoder speed alarm outputs.
Alarms can be output for upper and lower speed limits.
The speed alarm outputs are assigned to cam outputs as shown in
the following table. The speed alarms are set to “- - -” for the default
settings, i.e., the normal cam outputs are enabled. If a speed alarm is
set to any value but “- - -”, the normal cam output for the
corresponding cam number will be disabled.
The setting ranges for the upper and lower limits speed alarm are
given in the following table.
Note:
Default settings are shown in reverse type.
Speed Alarm Upper Limit (
f3
)
The upper limit set value is set using the F3 menu in the Function
Setting Mode.
Upper Limit Setting Display
Note:
If banks are being used, the bank number must be set.
Speed Alarm Lower Limit (
f4
)
The lower limit set value is set using the F4 menu in the Function
Setting Mode.

Note:
If banks are being used, the bank number must be set.
