PMAC2-PCI physical front

Overall appearance of the board
1、 Basic Information
Model: PMAC2-PCI (part number 400-603367-10X)
Brand: Delta Tau (now owned by Omron)
Positioning: PCI bus type 8-axis independent motion control card, dedicated for digital pulse/PWM, different from old-fashioned ± 10V analog PMAC-PCI
Architecture: Mother child board structure (lower full-size PCI board+upper CPU board), CPU board can be upgraded to Turbo high-performance version
Bus: 33MHz 32-bit standard PCI, industrial computer universal 5V PCI slot
Power supply: PCI slot 5V power supply, maximum power consumption of the whole machine is about 3.5A
Axis capability: Onboard native 4-axis circuit, with ACC-8P expansion daughter card that can be extended to complete 8-axis control
Factory firmware: PMAC2 firmware, supporting linear/circular interpolation, electronic cam, multi axis synchronization, PLC backend logic
2、 Core hardware parameters
1. Main control and storage
CPU: Standard 40MHz DSP563xx; High end 5E3 option with 160MHz DSP56311
Memory: 128K x 24 bit zero wait SRAM; 512K x 8-bit Flash (firmware/program storage); 2K × 8-bit EEPROM (parameter power-off saving)
Clock accuracy: ± 100ppm, stable servo cycle
2. Single axis output mode (software can freely switch between each axis)
The PMAC2 series has a unique three choice output, with a single axis independent configuration:
Pulse+direction: compatible with stepper drivers and pulse type servos
Three pairs of PWM direct output: direct drive brushless servo power level
Dual serial DAC output: external ± 10V analog servo drive
3. Encoder feedback (8-axis independent channel)
Signal: differential/single ended AB orthogonal+Index zero position, supports incremental encoder
Supporting functions: Hardware location comparison output (EQU signal, dedicated for flying and synchronous cutting)
Input isolation: differential anti-interference, suitable for high interference working conditions of machine tools and semiconductors
4. Onboard I/O (single axis standard)
Each axis comes with a dedicated marking signal:
9-way digital input: positive and negative limit, origin, driver failure, emergency stop, etc
2-channel digital output: servo enable, alarm reset
Expansion port: multiplexed I/O, external 8-18-bit ADC acquisition analog sensor
5. Communication interface
PCI local bus: high-speed interaction with the upper computer, supporting dual port RAM (2B option, high-speed real-time data)
RS232 serial port (IDC10 interface, ACC-3L to DB9): offline independent operation, no PC debugging
3、 Core functions of motion control
Interpolation: line, arc, spiral, spline interpolation, multi axis linkage
Servo algorithm: PID+notch filtering+speed/acceleration feedforward to suppress resonance
Synchronization function: electronic gear, electronic cam, spindle synchronous flying shear, follow-up tracking
Program system: PMAC G code motion program+backend PLC loop logic
Servo cycle: standard 4kHz closed-loop refresh, high-precision micrometer level positioning
4、 Supporting accessories (achieving complete 8-axis)
ACC-8P: 4-axis extension shaft interface card, installed from 4-axis to 8-axis
ACC-3L: Serial IDC10 to DB9 debugging cable
ACC-65E: 8-axis JMACH terminal board, adapter encoder/pulse/limit signal
ACC-24P: Remote Axis Expansion Board (MACRO bus, expandable to 32 axes)
5、 Can it be used directly on the computer? Divided into brand new/second-hand
1. Brand new original PMAC2-PCI
The hardware can be directly inserted into the PCI slot of the industrial computer, but it cannot run immediately after power on. The complete software process is required:
Shut down and insert the idle 5V PCI slot, fix the baffle;
Start up and install the driver PComm32 PRO;
Install and debug PeWin32 Pro2 software;
P2Setup wizard to configure the number of boards, axes, and output modes;
Download motor parameters PID、 Motion program, set the servo and put it into use.
2. Disassemble second-hand/refurbished cards
It is strictly prohibited to directly use the machine, and all items must be tested:
Check whether PCI bus communication and serial communication are normal;
4/8-axis pulse PWM、 Verify the continuity of each encoder channel one by one;
Flash and EEPROM read and write tests confirm that parameters are not lost;
Long term aging under full load, check DSP and capacitors for no heating or bulging;
Verify that the firmware is not damaged, clear the old device parameters, and reconfigure.
6、 Key differentiation from old PMAC-PCI (avoid mixing)
Table
Model output type adaptation driver core differences
PMAC2-PCI pulse/PWM/serial DAC stepper, digital servo, analog servo multi-mode digital output, 8-axis expansion
PMAC-PCI only has a single ± 10V DAC for traditional analog servo without pulse output, with only 4/8-axis analog signals
7、 Typical application scenarios
Semiconductor equipment, CNC machine tools, laser cutting, multi axis robotic arms, printing flying shears, lithium battery winding equipment, high-precision automated production lines.
