Part2: BCL3766 Wiring Instructions
The External IO Board of BCL3766 is installed by rail and also can be installed permanently. Its external size is 315mm*128mm with DM62M and DB37M interface in two sides, corresponding to JP1 and JP2 of BMC1604V2. C62-2 cable is used to connect External IO Board DB62 interface with JP1 port on the back of control card JP2 interface is linked by C37-40 baffle wire and then is fixed on erection fixture of computer with bolts. And C37-2 cable is used to connect DB37 socket on External IO Board.
The four DB15M interfaces on the top left corner are servo control signals, which are X axis, Y axis and W axis, respectively, from left to right. When being used as gantry dual drive, W axis is as Y2 axis. When being used as pipe cutting, W axis is as rotation axis.
High-low terminals on bottom left are respectively limit and origin signal of X axis and Y axis. High-low terminals on upper right are origin and limit input of W axis and general input interface, with all the low terminals break-over, as COM ground, namely 0V.
The interface on bottom right is 20 general outputs, thereto, 8 outputs as relay output, 12 outputs as mosfet output. The first 4 ones of the 8 relay outputs only have normally open contacts and the second 4 outputs have normally open contacts and the second 4 outputs have normally open contacts and normally closed contacts. The 8th mosfet output is 24 V general cathode output.
The three 2–pin terminals over right above are 1 PWM and 2 DA analog signal.
Dip switch:
There is a 4-bit dip switch below the PWM and DA analog signal. Its usage is shown as below :
The first bit (P1) and second bit (P2) of 4-bit dip switch choose PWM voltage.
2.2 Signal type
2.2.1 Input signals
Input signals include: limit, origin and general input. The input of BMC1604 V2 card is active low level: support normally open and normally closed mode (The polarity of input port can be modified by “platform configuration tool” of CypCut software). When the setting is normally open, input port and 0 V break-over are active; when the setting is normally closed, disconnection of 0 V is active.
Input port polarity can be modified through the hardware jumper. Now IN13, IN14 and IN15 input ports support this function. Jumper has two states, ACT_LOW as shown in the figure, which means low level is active (inputting 0V voltage is active); ACT_HIGH as shown in the figure, which means high level is active (inputting 24V voltage is active). Default state is ACT_LOW.
Typical connection of optoelectronic switch is shown as below, which must use 24V switch of the NPN type (low level is active).
Typical connection of contact switch is shown as below:
Typical connection of magnetic switch is shown as below, which must use 24V switch of the NPN type.

2.2.5 Analog output signals
There are 2 outputs of 0~10V analog signal in the External IO Board.
2.2.6 PWM output signals
BCL3766 External IO Board has 1 PWM pulse width modulating signal which can be used for controlling average power of fiber laser. PWM signal level is 5 V or 24 V for selection. Duty cycle is 0%~100% and the highest carrier frequency is 50 KHz. The output way of PWM signal is shown as below:
We strongly recommend that users install PWM+/- signal to a relay output port in series (Set it to PWM+/- enable signal.), then access to the laser, which can avoid laser light leakage in modulation mode. Please refer to “2.5 Laser Connection” for more details. Furthermore, please adjust PWM signal level. 24 V or 5 V level can be selected through dip switch.
2.3 Terminal Instructions
2.3.1 External power source
External power source provide direct current 24 V for BCL3766 External IO Board. 24 V and COM of power input terminal are connected to 24 V and 0V of power output interface, respectively.
2.3.2 Servo control interface
The four servo control interfaces on BCL3766 are DB15 two-row bores, and pin definition is as below:
The signal definition of matched servo cables is shown as below:
+24V,0V: Supply 24V DC power for servo drive; SON:
The output is servo enable signal when servo on; ALM:
Alarm, receive servo alarm signal;
PUL+, PUL-: Pulse (PULS), differential output signal;
DIR+,DIR-: Direction (DIR), differential output signal;
A+, A-, B+, B-, Z+, Z-: Three phase of encoder, input signal;
The polarity of SON and ALM signal can be modified through hardware jumper.
When the SON signal jump to ACT_LOW state, low level is active (inputting 0V voltage is active); When the SON signal jump to ACT_HIGH state, high level is active (inputting 24V voltage is active). Default state is ACT_LOW.
When the ALM signal jump to ACT_LOW state, low level is active (inputting 0V voltage is active); When the ALM signal jump to ACT_HIGH state, high level is active (inputting 24V voltage is active). Default state is ACT_LOW.
Please refer to “1.3.3 The wiring diagram of servo drive control signal” for connection of Panasonic, Yaskawa, Mitsubishi and Delta servo drivers.
Please pay attention to the following information when connect servo driver of other brands:
- Please confirm the type of servo driver SON signal you select whether low level is active or not. (That is, It is ON when connecting with 24V GND.)
- Confirm the parameters of servo driver are set as: the type of received pulse signal is “pulse + direction”
- Confirm whether t h e servo driver input terminal has external crash stopping signal input or not, and which logic the signal is.
- Before the trial operation of servo driver, 24 V power must be provided for External IO Board, for 24 V power servo driver needs is provided by External IO Board.
- If driver still cannot run, confirm that driver parameter is set as not using “positive & negative input inhibit”.
- Connect shielding layer of signal line with servo driver case.
2.3.3 The wiring diagram of servo drive control signal
FSCUT2000 Fiber Laser Cutting Control System motion control system apply the signal of “Pulse+Direction” to control servo driver. The pulse sending frequency cap is increased from the previous 750Kpps to 3Mpps.
Recommend using high-speed differential pulse signal, and setting the pulse equivalent of servo driver in 1000 ~2000, in order to improve the interpolation accuracy.
The maximum pulse frequency of Mitsubishi J3 series is 1Mpps.
Note:
Parameter settings above can guarantee basic sports only under the circumstances of the right wiring connection, not ensure control precision. And if you need to further optimize campaign results, please adjust the rigidity, gain, inertia ratio and other parameters.
