AG SERVO AMPLIFIER COMPATIBLE WITH ANALOG INPUT
Used to set the encoder pulses (A-phase or B-phase) output by the
servo amplifier.
Set the value 4 times greater than the A-phase or B-phase pulses.
You can use parameter No. 54 to choose the output pulse designation
or output division ratio setting.
The number of A/B-phase pulses actually output is 1/4 times greater
than the preset number of pulses.
The maximum output frequency is 1.3Mpps (after multiplication by
4). Use this parameter within this range.
For output pulse designation
Set " 0 " (initial value) in parameter No. 54.
Set the number of pulses per servo motor revolution.
Output pulse set value [pulses/rev]
At the setting of 5600, for example, the actually output A/B-phase
pulses are as indicated below:
A B-phase output pulses
For output division ratio setting
Set " 1 " in parameter No. 54.
The number of pulses per servo motor revolution is divided by the
set value.
Resolution per servo motor revolution
Output pulse
At the setting of 8, for example, the actually output A/B-phase
pulses are as indicated below:
A B-phase output pulses
TL1 Internal torque limit 1
Set this parameter to limit servo motor torque on the assumption
that the maximum torque is 100[%].
When 0 is set, torque is not produced.

1 :on
When torque is output in analog monitor output, this set value is the
maximum output voltage ( 8V). (Refer to Section 15.2.5, (1)(c))
VCO Analog speed command offset
Used to set the offset voltage of the analog speed command (VC).
For example, if CCW rotation is provided by switching on forward
rotation start (ST1) with 0V applied to VC, set a negative value.
When automatic VC offset is used, the automatically offset value is
set to this parameter. (Refer to Section 15.5.3.)
The initial value is the value provided by the automatic VC offset
function before shipment at the VC-LG voltage of 0V.
Analog speed limit offset
Used to set the offset voltage of the analog speed limit (VLA).
For example, if CCW rotation is provided by switching on forward
rotation selection (RS1) with 0V applied to VLA, set a negative value.
When automatic VC offset is used, the automatically offset value is
set to this parameter. (Refer to Section 15.5.3.)
The initial value is the value provided by the automatic VC offset
function before shipment at the VLA-LG voltage of 0V.
