Note:
Stall prevention during decel increases the deceleration distance even when the bus voltage remains at
the nominal level. For this reason, it is important to leave L3-04 set to “Disabled” (0).
Note:
The ENTER command is not required when writing to these registers.

Address
Description
Scaling
061Ch
Modbus Communication Speed Reference during a Move. Effective only when P1-02 = 2.
0.01 Hz
100 = 1.00 Hz
061Dh
Modbus Communication Position Reference (Engineering Units)
Actual position reference in encoder counts = 61Dh * P1-09.
Range is: 0.00 ~ 655.35 units. Effective only when P1-02 = 2.
0.01 Units
100 = 1.00 Units
061Ch
Modbus 32-bit Communication Position Reference (low word). Effective only when P1-02 = 3.
Quadrature
Encoder Counts
061Dh
Modbus 32-bit Communication Position Reference (high word). Effective only when P1-02 = 3.
0734h
32 Bit Distance From Home (low word)
Distance from home (+ home offset) for absolute applications, or distance from start of previous
move for relative applications. Read only.

Motion Control Modbus Status Register
Bits 0 ~ 5 are a copy of the information in monitor U1-11. Bits 6 ~ C behave the same as the
motion control digital outputs (H2-0X = 40 ~ 46). Read only.
Bit 0: Digital Output Status – M1-M2
Bit 1: Digital Output Status – M3-M4
Bit 2: Digital Output Status – M5-M6
Bit 3: Digital Output Status – P3-C3
Bit 4: Digital Output Status – P4-C4
Bit 5: Not Used
Bit 6: Not Used
Bit 7: Digital Output Status – MA-MB-MC (fault)
Bit 8: Move In Progress
Bit 9: Move Complete
Bit A: Homing Complete
Bit B: Homing Needed
Bit C: At Home
Bit D: Learn Successful
Bit E: Pre-Action Output
Bit F: Not Used
