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.

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.
