Control Specifications
The controller (GC-201, GC-101) is operated by:
•
RS-232C command input
•
High-speed serial communication
In addition, either the internal clock or external clock (high-speed serial communication) can be
selected for operation.

With the default settings at shipping, power-on activates the controller with the internal clock.
The parameter can be set so that the controller starts with the external clock after power-on.
For activation with the external clock, however, signal input by high-speed serial communication is
necessary at power-on.

•
Parameter setting
•
Error processing
•
Status check
(For details, see 7, “Commands.”)
If position data send by high-speed serial communication is disabled, RS-232C command input is

High-speed serial communication
To control the mirror to an arbitrary position by Marking or any other application, target position data
updated as required can be given to the controller by using high-speed serial communication.
By setting, the controller can be activated in the mode of tracking a target position specified by
high-speed serial communication. (For details, see 6-1, “Setting Activation Mode.”)

With the default settings at shipping, the setting is ※ (16bit position data length, data least
significant bit 1bit position).
This communication specification has compatibility of XY2-100.
When using the scanner controller of XY2-100 specifications, please use this setting.
Motor rotating angle for the high-speed serial communication data
・ In the case of 16bit position data
Data: 1 for one pulse that can be specified up to the following positions:
Maximum position:
0xFFFF = 32767 pulses = About 5.76 deg (GM-1010)
0-pulse position:
0x8000 = 0
Minimum position:
0x0000 = –32768 pulses = About –5.76 deg (GM-1010)
If a greater angle is specified, set a magnification by using the High-speed Serial Communication
Conversion Gain parameter (Parameter ID = 13)
E.g.
For x2 (Setting: 2000), the following angle can be specified:
–5.76 × 2 deg
to 5.76 × 2 deg
The command resolution will be two times.
・ In the case of 20bit position data
Data: 1 for one pulse that can be specified up to the following positions:
Maximum position:
0xFFFF = 524287 pulses
0-pulse position:
0x8000 = 0
Minimum position:
0x0000 = –524287 pulses
Maximum movable range is set with Parameter ID = 0, 1 (CW limit, CCW limit).
The position data of high-speed serial communication can not exceeded this range.

2.8.
Heat Radiation and Installation
Since the controller and motor generate heat, their heat radiation should be considered carefully.
Generated heat depends on the operating conditions. Determine a heat radiation method according to
the operating conditions.
The controller and motor have a temperature detection sensor (thermistor) at the heat generating
section. As a safety function, the thermistor stops control if the detector temperature reaches:
Controller
About 70ºC
Motor
About 70ºC
(For details, see 9, “Safety Functions.”)
The controller and motor require heat radiation so that their temperatures will not exceed the above values.
Controller installation methods
The controller can be installed by either Method A or B below.
At installation, put the controller frame in contact with a heat-radiating structure (heat sink or cabinet).
Method A has higher heat radiation efficiency. However, select either method by considering the
operating conditions and cable routing. When installing the controller frame, apply thermal grease or
attach a thermal conductive sheet to the contact surface.
Under some operating conditions, forced air cooling by a fan is necessary. Cool the heat-radiating
structure (heat sink or cabinet) and the controller.
A
B
Output amplifier
Control circuit
In addition to the output amplifier, which is the main source of heat, the control circuit section (DSP)
generates heat.
Allow as much space as possible around the equipment.
Caution
The controller becomes hot during operation.

3. Software
The controller (GC-201, 101) comes with dedicated control software “GALILEO (Galvano Integrated
Leading Operator (GALILEO).”
GALILEO makes the following controller operations easy:
・Parameter setting
・Servo tuning (Frequency characteristic measurement)
・Status check
・Operation setting (Step movement and raster scan)
Most of the functions that can be performed by GALILEO can also be executed by external command
input through RS-232C connection without using GALILEO. This manual describes operations both by
GALILEO and by external command input.
Note: The following function can be executed by GALILEO only, and not by external command input:
・Frequency characteristic measurement

This chapter explains how to use the system.
Operations by [GALILEO] and by [RS-232C command] are explained together.
4.1.
Controller Activation
When the power (+5 V, +24 V) is turned on, the controller first does the following automatically:
・Reads saved parameters from ROM
・Homes to the origin
・Corrects the encoder (high-speed oscillation of a fixed angle)
It takes about 15 seconds until the controller is activated.
With the default settings at shipping, the controller is activated with the internal clock.
The completion of activation can be confirmed as follows:

0: Internal clock
1: High-speed serial communication
P64 = 1: Activation with internal clock
P64 = 3: Activation by high-speed serial communication
(Bit 0 of P64 is used to enable or disable encoder correction when homing to the origin; it is usually set
to 1. For details, see 8-2, “Parameter Details.”)
Activation mode
Power-on usually executes the following automatically:
・Reading parameters from EEPROM
・Starting homing and servo control
If there is a problem with the parameters read from EEPROM or if oscillation occurs when homing and
servo control are executed automatically, the power-on activation mode can be changed.
For this switching, the switches (SW1 and SW2) on the controller board and the logic of the digital I/O
terminal (A6) are combined.

Operation that synchronizes with external trigger Signal input(Raster Scan)
“4-3. raster scan operation”, It can be operated synchronizing with external trigger Signal.
【The Movement Pattern】
There are two kinds of movement patterns.
①(The raster scan of one coming and going operates whenever the external trigger signal is input.)
Angle

(Current Angle Position)
Voltage
External Trigger Signal
②(The raster scan of one way operates whenever the external trigger signal is input.)

This command is also used for a return from high-speed serial communication
mode to internal clock mode. In the case of two axis control, it is necessary to
execute this command for each axis.

Raster scan starts after step movement to the scan initial position.
Explanation
7: High-speed serial communication mode
This command switches the mode to high-speed serial communication from

The controller status is always monitored by software and error notification is made if an abnormality
occurs.
Depending on the error type (priority), digital monitor I/O (2 bits) is used for this notification.
The details of an error can be checked by an RS-232C command.
See 9-2 for the error contents.
Note: The post-error system status and recovery method depend on the priority of the error.
See 9-2, “Errors.”
