ELAU PacDrive C600 Controller Integration Guide

2. Environmental conditions

The environmental tolerance of C600 is classified according to IEC/EN 60721-3 standard:

Conditional operation (3K3) Transportation (2K3) Long term storage (1K4)

Environmental temperature+5 ° C...+45 ° C -25 ° C...+70 ° C -25 ° C...+55 ° C

Relative humidity 5%... 85% 5%... 95% 5%... 95%

Condensation, freezing, and water are prohibited

Attention: If UPS is selected, the upper limit of operating temperature is reduced to+40 ° C and the upper limit of storage temperature is reduced to+45 ° C.

3. Mechanical specifications

Dimensions: The packaging dimensions are 300 mm (depth) x 130 mm (width) x 400 mm (height), and the body weight is approximately 3.5 kg.

Protection level: The shell is IP20 and is only suitable for installation inside the control cabinet to prevent metal shavings, water droplets, etc. from entering.

Installation method: Fixed with standard DIN rails or bottom plate screws.

Programming and Engineering Software

The PacDrive C600 fully complies with the IEC 61131-3 international standard and supports all five programming languages:

Instruction List (IL)

Ladder diagram (LD)

Function Block Diagram (FBD)

Sequential Function Diagram (SFC)

Structured Text (ST)

And additional support for Continuous Function Diagram (CFC)

The engineering software is EPAS-4 (ELAU Programming and Automation System), which integrates PLC programming, motion parameter configuration, SERCOS bus debugging, HMI variable linking, and online monitoring functions. The software is built-in with:

8-channel software oscilloscope (Trace Recorder): resolution of 1 ms, capable of recording variable curves.

27 kB diagnostic data logger: Loop records system events and error messages.

OPC Server: Provides data access for third-party HMI.

For remote maintenance, the C600 has a built-in modem interface (requiring an external modem), which can be dial-up connected through a telephone line to achieve remote diagnosis, program download, and web access.

Key points of wiring and prevention of common errors

According to the connection table in the manual, the following wiring details are prone to errors and require special attention:

1. Power connection X1

Pin1 (DC 24V) and Pin3 (+UL) must be connected simultaneously, even if the digital output is not in use, the+UL should still be connected, otherwise some internal logic may not work properly.

If the current demand is high (such as driving multiple solenoid valves simultaneously), Pin1 and Pin2 can be used in parallel with Pin5 and Pin6 through external short circuiting, with a maximum current carrying capacity of 4A.

2. Polarity of digital input/output

All digital inputs and Touchprobe inputs are source type (PNP), meaning the common terminal is 0V and the signal terminal is connected to 24V effectively. Do not connect NPN type sensors, otherwise intermediate relays need to be added for conversion.

The digital output is also source type, and when the output terminal is conductive, it outputs 24V (relative to the common terminal 0V). Connect one end of the load to the output terminal and the other end to 0V.

3. Analog input wiring

Voltage measurement: directly connect AI+and AI -.

Current measurement: AI+and J.0+must be short circuited, and AI - must be connected back to A.GND. Otherwise, the correct reading cannot be obtained.

4. PROFIBUS DP bus (X20)

PROFIBUS specific connectors with terminal resistors must be used. The terminal resistors of the first and last nodes of the bus must be turned to the "ON" position, and the middle node must be turned to the "OFF" position.

The shielding layer must be grounded extensively at both ends and cannot be grounded solely through the DB9 casing.

5. PacNet bus (X12, X13)

Only ELAU certified dedicated PacNet cables are allowed to be used, and ordinary Ethernet cables should not be used as a substitute, otherwise it may cause communication failures or bus conflicts.

6. Real time clock battery

The controller has a real-time clock (RTC) battery inside, with a maintenance cycle of 5 years. After expiration, the service department should be contacted for replacement, otherwise the system time may be reset after power failure.

Troubleshooting and maintenance recommendations

1. Common fault phenomena and countermeasures

Possible cause investigation steps for the phenomenon

The controller cannot start, the display screen shows no indication that the 24V power supply is not connected or the voltage is too low. The Pin1-Pin2 voltage of X1 should be 20.4-30V. Check the external circuit breaker

Random shutdown during operation, watchdog relay releases CPU overheating, memory error, software abnormality to check if control cabinet temperature exceeds 45 ° C; reads diagnostic buffer through EPAS

SERCOS communication interruption, fiber optic damage, connector contamination, and inspection of fiber bending radius in case of substation power failure; Clean the connector; Check the status LED of MC-4 driver

Unstable PROFIBUS communication with incorrect terminal resistance settings, poor shielding, and address conflicts. Confirm that the terminal resistance of the first and last stations is ON. Check the grounding of the shielding layer; Scan bus address
