The PacDrive PS-5 incorporates multiple safety features to protect both equipment and personnel:
Residual DC Bus Voltage Display: An LED indicator warns when dangerous voltages (>50V DC) are present in the DC bus.
Leakage Current Protection: With leakage current greater than 3.5 mA, the unit requires a fixed connection to the power supply network in accordance with DIN EN 50178 standards.
Comprehensive Safety Standards Compliance:
EN 60204-1 (2007): Safety of machinery - Electrical equipment
EN 50081-2 (3/1994): Electromagnetic compatibility
EN 61000-6-2 (3/2000): Electromagnetic immunity
The manufacturer's declaration confirms that the PS-5 is intended for installation in machines and complies with EC machine guidelines 98/37/EC. Commissioning is prohibited until it's confirmed that the host machine meets all EC Directive requirements.
Proper installation of the PacDrive PS-5 requires attention to several critical factors:
Grounded Operation: May be operated without potential separation on AC networks with a grounded star point
Ungrounded Mains: Requires an isolating transformer when operating on IT networks or mains without grounded neutral points
Use of a fuse (Type: maximum 40 A, 600 VAC) in the feed line
Operation only on circuits capable of delivering ≤5000 rms symmetrical amperes
For 24V supply, use a fuse with max. 15 A
The PS-5 features multiple connection points with specific requirements:
| Connection | Meaning | Max. Terminal Cross-section | Max. Torque |
|---|---|---|---|
| X1 | Control voltage/Mains | 0.2-10 mm² rigid / 0.2-6 mm² flexible | - |
| X2 | Bleeder connection | 0.2-10 mm² rigid / 0.2-6 mm² flexible | - |
| X3 | ISH connection | 0.2-10 mm² rigid / 0.2-6 mm² flexible | - |
| X4 | SERCOS LWL IN | - | 0.8 Nm |
| X5 | SERCOS LWL OUT | - | 0.8 Nm |

| X8 | Control signals | 0.14-1.5 mm² | - |
The PS-5 features a comprehensive LED indicator system for status monitoring and diagnostics:
OFF: Control voltage missing or too low
Slow Flash (0.5 Hz): Bootloader active, firmware defective
Brief Flash (3 Hz): Device identification active
ON: Device ready, error diagnosis possible
OFF: No error
Slow Flash (0.25 Hz): SERCOS error
Quick Flash (2 Hz): General error or device not configured
Long Flash: SERCOS ring interruption
ON: Fatal system error
BUS ERR: Indicates fiber-optic cable connection problems
SINK: Shows SERCOS bus state (copper cable)
SERR: Displays errors for copper cable SERCOS connection
The PS-5 requires careful attention to electromagnetic compatibility:
Use shielded cables only with proper grounding
Implement star configuration grounding from central point
Avoid cable loops in switch cabinets
Maintain short motor cable lengths
Isolate controller from interference sources when necessary
While largely maintenance-free when correctly installed, the PS-5 requires:
Periodic cleaning with dried compressed air (max 1 bar)
Annual checks of brake functions (if present)
Regular verification of safety functions (EMERGENCY OFF, etc.)
Maintenance logbook entries for all component replacements
The PacDrive PS-5 serves as a central component in the PacDrive system architecture, which includes:
PacDrive Controllers: Microprocessor-based control hardware with VxWorks RTOS
PacDrive Servo Amplifiers (MC-4)
PacDrive Motors
Distribution Box DB-5: Links between PS-5 and iSH modules
The system supports various HMIs and can coordinate multiple drives depending on controller model (C200: 8 drives, C400: 16 drives, C600: 99 drives).
The ELAU PacDrive Power Supply PS-5 represents a robust, feature-rich solution for industrial automation power distribution. Its combination of safety features, diagnostic capabilities, and flexible integration options make it particularly suitable for packaging and food processing machinery where reliability and precision are paramount.
