Accessing Data

Parameter values are returned in the same engineering units as the SEW drive supplies. Values written must also match the expected engineering units. [g3-sew | Word]

• Select the parameter and service from the list
• IPOS Variables use Data Item H (H0–H511)
• Index selections (8300–25000) use Data Item I
• Process data uses Data Items:
  • PD (output data)
  • SPD (send process data) [g3-sew | Word]

Service Codes

Available services:

• Read/Write
• Read/Write Volatile

Warning:
Use Read/Write sparingly — the drive memory supports a limited number of write cycles. [g3-sew | Word]

Process Data Access

For correct operation:

• Parameter 100 (Setpoint Source) → RS485
• Parameter 101 (Control Signal Source) → RS485

Key notes:

• Process output data initializes to 0 at power-up
• Assign process output data to a write-enabled tag
• Use SPD to define:
  • Data length
  • Transmission type
• Enable cyclical transmission for timeout monitoring
• Always clear (set to 0) SPD after each non-zero write [g3-sew | Word]

Process data can be read from:

• Parameters 094–096 (output data)
• Parameters 097–099 (input data) [g3-sew | Word]

Special Parameter: Latest Exception Code (9999)

Parameter 9999 stores the most recent communication exception:

• Upper 16 bits → Index
• Lower 16 bits → Exception code [g3-sew | Word]

Exception Codes

Example:

21140015

Indicates parameter index 2114 with error code 15. [g3-sew | Word]
