3. INTERFACE AND COMMUNICATION CONFIGURATION
3.1 Main Circuit Terminals
R/S/T: Three-phase AC main power input terminals; U/V/W: Servo motor three-phase power output terminals; P/N: External braking resistor expansion terminals.
3.2 Signal Connectors
CN1 (I/O terminal block): 8 opto-isolated digital inputs and 6 relay-type digital outputs; I/O logic pre-configured per Y367 custom definition for matched equipment. Available functions: Servo Enable, positive/negative overtravel limit, home signal input, emergency stop, fault output and servo ready signal.CN2 (PG encoder port): Dedicated connector for multi-turn serial absolute encoder 5V differential feedback wiring.
3.3 Communication & Command Interface
Primary command mode: digital differential pulse positioning input (standard SS feature); auxiliary analog speed/torque input reserved for backup use.Built-in proprietary Yaskawa RS422 communication for parameter reading/writing, runtime status monitoring and historical fault inquiry; optional expansion module supports Modbus-RTU bus connection.
4. CORE FUNCTIONS
Three adjustable control modes: position control for precision fixed positioning, speed control for constant-speed conveying, torque control for constant tension control; electronic gear ratio available for multi-axis synchronous movement.
Automatic motor parameter tuning: one-click identification of motor electrical parameters and rotor inertia for automatic loop gain optimization.
Absolute position memory: power-off position retention removes homing operation after equipment restart, core advantage of Z coding.
Internal integrated braking circuit absorbs regenerative energy during deceleration; external resistor only necessary under frequent heavy-duty emergency stop scenarios.
Y367 customized setting: factory pre-set loop gain, acceleration/deceleration values and function parameters matching the target OEM machine to reduce on-site debugging workload.
Historical fault storage: stores latest 10 fault codes for after-failure maintenance diagnosis.
5. APPLICABLE SCENARIOS
Customized for designated automatic precision equipment specified by Y367 project code, mainly small special-purpose CNC auxiliary feed axes, customized electronic assembly machines, dedicated miniature gantry positioning equipment and special labeling automation production lines.
6. OPERATION AND MAINTENANCE INSTRUCTIONS
6.1 Pre-operation Check
Check all power, encoder and I/O cables for short circuit, loose terminals or misconnection before power-up. Do not arbitrarily modify pre-set Y367 factory parameters unless mechanical structure is altered; complete trial run verification after wiring inspection.
6.2 Daily Operation Requirements
Ensure cabinet ventilation is unobstructed; avoid continuous operation when internal cabinet temperature exceeds 55℃; prevent frequent repeated power ON/OFF in short periods.
6.3 Periodic Maintenance (every 3–6 months)
Tighten loose terminal screws, inspect cable insulation aging and surface crack, clean accumulated dust on drive heat sink and cabinet air vents. Cut off main AC power and wait at least 15 minutes for full discharge of internal DC bus capacitor before any internal disassembly to avoid electric shock risk. Halt equipment and cut power immediately under persistent fault alarm; inspect motor, wiring and mechanical jamming before restarting.
7. COMMON FAULT TROUBLESHOOTING
Overheat alarm: clogged heat sink, excessive ambient temperature or long-term overload operation.Encoder fault alarm: loose CN2 connector or damaged absolute encoder cable.Overvoltage alarm: frequent rapid deceleration with heavy load; fit external regenerative resistor onto P/N terminals.
