ABB 3HAC029818-001 DSQC663 Input & Output Interfaces
Power Input
Main AC power input: 3-phase AC 380–480V, 50/60Hz, connected via cabinet power bus terminal block
Control logic power input: 24V DC low voltage supply from IRC5 power supply unit
DC bus internal input: Rectified high voltage DC bus power from cabinet rectifier module
Feedback signal input: Resolver analog position signals / encoder digital signals from each robot joint motor
Internal bus command input: Real-time motion control instructions from IRC5 main computer board via internal rack backplane bus
Temperature sensor input: Built-in thermistor temperature detection signal input for overheat protection
Digital fault input: External cabinet safety chain, emergency stop, cabinet door interlock logic signals
Power Output
Six independent servo motor power output channels (U/V/W phase) for 6 robot joint axes, continuous rated 15A, peak 45A within 10s
DC bus voltage output signal to main control board for voltage monitoring and overvoltage protection
Phase current sampling output signals for real-time current closed-loop control and overload diagnosis
24V auxiliary power output for internal drive circuit and signal conditioning circuits
Signal Output
Axis motion status output: Digital fault codes, overheat, overload, overvoltage, undervoltage alarm signals transmitted via backplane bus
Position feedback processing output: Converted digital position data to IRC5 main controller
Communication signal output: Industrial real-time bus data exchange signals to IRC5 system board
Hardware fault relay output: Dry contact alarm signal for drive unit critical failure notification
PWM drive pulse output to internal power switching IGBT modules for motor speed/torque regulation
ABB 3HAC029818-001 DSQC663 Installation Method
Applicable installation carrier: Special internal rack of ABB IRC5 robot control cabinet, no independent external mounting support.
Mounting type: Vertical slide-in plug-in modular installation.
Pre-installation preparation: Align the slide rails on both sides of DSQC663 with the guide slots of the cabinet drive rack.
Insertion operation: Push the module horizontally backward along the guide rails until the rear golden connector completely fits the cabinet backplane bus interface.
Fixing step: Tighten four fixing screws distributed on the front panel of the module to lock the unit onto the rack frame.
Post-installation wiring: Power cables and motor servo cables are connected to the wiring terminals reserved at the bottom of the module.
Space requirement: Keep sufficient heat dissipation gap between adjacent drive modules on the rack after installation to avoid overheating.
