2. Installation
This chapter will describe the installation method, wiring method,
meaning of the indicator and meaning of the interface of the GC-2302 module.
2.1 Module fixing
The installation method of GC-2302 module as shown in Figure 2.1 and a
flat-blade screwdriver is needed for auxiliary installation.
Figure 2.1 Installation of GC-2302 module
First install the GCAN-PLC on the guide rail and plug the GC-2302 along
GCAN-PLC's right side until the lock is stuck.
The GC-2302 module needs to be used with a GCAN-PLC-400/510 or
GCAN-IO-8000 series coupler, and can be powered directly through the
coupler, so there is no need for a separate additional power supply.
2.2 Wiring method
The power wiring as shown in figure 2.2. First, use a flat-blade
screwdriver to insert into the square hole, hold the top edge of the metal sheet
in the square hole, and press toward the hole. Then, insert the wire into the hole.
After plugging in, pull out the screwdriver and the wire can be firmly locked in
the hole.

2.3 System status indicator
GC-2302 module has no error indicator light. Please judge the status of
GC-2302 module by "IORUN" and "IOERR" indicator lights of the GCAN-
8000 series coupler. If the "IO ERR" indicator of the GCAN-8000 series
coupler is on, please check the installation of the module.
2.4 Method ofuse
Work with GCAN-PLC
GC-2302 module has three working modes :(see gc-2302 module routine for
details)
Speedmode
Locationmode
Pulse output mode

Guangcheng Technology GC-2302 user manual
1. The working mode of speed and location are similar.
The variable declaration area of the program is defined as follows speed1
at%Q0.0:int; (*Define the 1st speed signal *)
pos1 at%Q2.0:dint; (*Define the 1st position signal *) speed2 at%Q6.0:int;
(*Define the 2nd speed signal *)
pos2 at%Q8.0:dint; (*Define the 2nd position signal *)
(1) First call the motor pulse initialization function block in the program:
EXT_MOTOR_PWM_INIT
EN_IN: Function block enable signal
NETNUMBER: Number of GC-2302 modules from PLC
MOTOR_CH: the pulse output number of the gc-2302, 1 or 2 MOTOR_MODE:
1 speed mode; 2 location mode; 3 Pulse outputmode
MOTOR_PULSE: The number of pulses required for one turn of the motor
ACCTIME: Acceleration time of rotation (ms)
DECTIME: Deceleration time of rotation (ms) FLEX: Slope rating
EN_OUT: The value is 1 after successful initialization
ERROR: error value
②After the initialization function block is executed without error, call the motor
enable function block: the input pin definition of the EXT_MOTOR_EN function
block:
EN_IN: Function block enable signal
NETNUMBER: Which GC-2302 module from the PLC
MOTOR_CH: The pulse output of the GC-2302, the value is 1 or 2
ENABLE: Enable signal of the motor
The output pin definition of the function block:
EN_OUT: The value is 1 after the function block is executed successfully
ERROR: error value
In the EXT_MOTOR_EN function block, only the input ENABLE is 1 to enable the
motor. After enabling, add the speed and position values to be defined: speed1, pos1,
speed2, pos2
(Note: If the motor enable ENABLE is 0 and speed and pos are not 0, there will still
be corresponding pulse output. Therefore, it is recommended to add the 0 statement
when the motor is not enabled in the program: speed1:=0, speed2:= 0,
pos1:=0, pos2:=0;)

2. The following describes the situation when the GC-2302 module is used for pure
pulse output: The variable declaration area of the program is defined as follows:
Pwm_Duty1 at%Q0.0:int; (*Define the duty cycle of the first pulse output, unit %*)
Pwm_FQ1 at%Q2.0:dint; (*Define the frequency of the first pulse output, unit: Hz* )
Pwm_Duty2 at%Q6.0:int; (*Define the duty cycle of the second pulse output, unit %*)
Pwm_FQ2 at%Q8.0:dint; (*Define the frequency of the second pulse output, unit: Hz
*)
First call the motor pulse initialization function block in the program: the input pin
definition of the EXT_MOTOR_PWM_INIT function block:
EN_IN: Function block enable signal
NETNUMBER: Number of GC-2302 modules from PLC
MOTOR_CH: the pulse output number of the gc-2302, 1 or 2 MOTOR_MODE: 1
speed mode; 2 location mode; 3 Pulse output mode
The output pin definition of the function block:
EN_OUT: The value is 1 after successful initialization
ERROR: error value
Next, assign values for duty cycle and frequency,
E.g:
Pwm_Duty1:=30; (*Duty cycle is 30%*)
Pwm_FQ1:=30000; (* frequency is 30kHz*)
Pwm_Duty2:=50; (* Duty cycle is 50%*)
Pwm_FQ2:=50000; (*Frequency is 50kHz*)
B. GC2302 is used in connection with GCAN-IO-8000 controller:
1. Motor initialization: CANopen main index: 0x3000
CANopen sub-index: 0
Send frame data: PDO parameter + main index + sub index + device number (the
number of GC2302 modules) + channel number
(Corresponding to the channel number of GC2302, channel 1 or channel 2) + pulse
value (the number of pulses required for 1 revolution of the motor) For example:
Device number: 1, channel number: 1, pulse: 5000
send pdo: 0x601 23 00 30 00 01 01 88 13
Device number: 1, channel number: 2, pulse: 5000
send pdo: 0x601 23 00 30 00 01 02 88 13
Device number: 2, channel number: 1, pulse: 5000
send pdo: 0x601 23 00 30 00 02 01 88 13
10
Guangcheng Technology GC-2302 user manual
Device number: 2, channel number: 1, pulse: 5000
send pdo: 0x601 23 00 30 00 02 02 88 13
2. Motor enable:
CANopen main index=0x3001
CANopen subindex=0
Send frame data: PDO parameter + main index + sub index + device number +
channel number + enable signal (0 or 1) + 00
For example:
Device number: 1, channel number: 1, enable: 1
send pdo: 0x601 23 01 30 00 01 01 01 00
Device number: 1, channel number: 1, enable: 0
send pdo: 0x601 23 01 30 00 01 01 00 00
Device number: 1, channel number: 2, enable: 1
send pdo: 0x601 23 01 30 00 01 02 01 00
Device number: 1, channel number: 2, enable: 0
send pdo: 0x601 23 01 30 00 01 02 00 00
3. Speed control:
Send PDO to control the motor speed. The speed value (2 bytes) needs to be
multiplied by a factor of 0.1. For example, if the speed value is set to 1000, the actual
motor speed is
：1000*0.1=100rad/min
For example: GCAN-8000 is connected to a GC2302 module, CANopenID is 1, the
speed of the first channel is 1000, and the speed of the second channel is 2000
Send PDO data: 0x201 E8 03 D0 07 00 00 00 00
If you need to shut down the first motor, send the PDO value as 0: 0x201 00 00 D0 07
00 00 00 00
