This is the terminal to input acommand voltage for scanner’s
position control.
In case of single ended input
referred to ground is selected,
make CN3-2 short-circuited with
CN3-3 (GND) and input positioncommand voltage to CN3-1.
This is the terminal to input
Servo ON / OFF.
When short-circuited against
GND, it would be Servo ON.
(Active LOW)

This is the terminal to output
LOW level when no error isgenerated.
It would output High level (DC(+)5V through protectiveresistance of 100Ω) when anerror is generated.

Volumes for Adjustments
The functions of the volumes are as follows:

Volume Name

PSSRL

EG

Content
Adjustment for Position Command Input Scale (Minor Tuning onFill-Scale Scanning Angle)
This allows to adjust position command input and position output ofvoltage scale. It also allows minor tuning on full-scanning angle at thesame time. The voltage-scale decreases by driving CCW (reduces themaximum scan angle).
The voltage error between position command input andposition output would be generated by this volumeadjustment.
Adjustment for Slew Rate Limiter on Position Command Input
This allows to adjust the response speed of the large step. The response
speed increases by driving CCW. The rate depends on the amount of load
inertia and current capacity of the power source.
Adjustment for Position Error Amplifier Gain
This allows to adjust acceleration while scanner is driving. Acceleration
would increase by driving CW.
Adjustment for Proportional Gain on Position Signal

SG

This allows to adjust first overshoot to be small under positioning control.

EL

Adjustment for Error Limiter
This allows to adjust response speed of large step. It is enabled only for P
Control. The response speed increases by driving CCW.

LFD

Adjustment for Position Signal Derivative Gain
This allows to adjust overshoot and undershoot to be small under positioning
control. It works effectively for low frequency components.

HFZ

HFDNFPFLIN

Minor Tuning for Frequency Band on Current Integration Feedback
SignalThis allows minor tuning on overshoot and undershoot to be small underpositioning control.
Adjustment for Current Integral Gain
This allows to adjust overshoot and undershoot to be small underpositioning control. This works effectively for high frequency components.
Adjustment for Center Frequency of Notch Filter
This allows to adjust the center frequency of notch filter to remove
resonance. The center frequency decreases by driving CW.
Adjustment for Position Signal Scale (Minor Tuning for Full-Scale
Scanning Angle)
This allows to adjust the gain of position signal which is input from thescanner. It also allows to adjust full-scale scanning angel at the sametime.
This volume adjustment may change initial setting
largely. Please contact our Sales representative before
the adjustment.
Correction of Linearity
We adjust non linearity to be less than 0.1% according to the pairing scanner
before delivery.
