Description

1

Main speed (VX)

Long
Float

Speed of main feedback sensor, in
counts/second.

2

Main position (PX)

Long
Integer

Cumulative position of main
feedback sensor, in counts.

external reference mode is set
(RM=1), this signal also includes
analog reference command.

4

Digital input pin status

Short
Integer

IP variable (see IP in the

SimplIQ for

Steppers

Command Reference Manual).

5

Position error (PE)

Long
Integer

Position tracking error: the difference
between main position reference and
main position feedback, in counts.

6

Current command (DV[1])

Short
Float

Current reference to current
controller, in amperes.

7

DC bus voltage

Short
Integer

Bus voltage, in volts.

8

Auxiliary position (PY)

Long
Integer

Cumulative position of auxiliary
feedback sensor, in counts.

9

Auxiliary Speed (VY)

Long
Float

Speed of auxiliary feedback sensor,
in counts/second.

10

Active current command (IQ) Short

Float

Active part of vectored current
reference, in amperes.

11

Reactive current command
(ID)

Short
Float

Reactive part of vectored current
reference, in amperes.

12

Analog input 1 (AN[1])

Short
Float

Analog input 1 after offset
compensation of AS[1], in volts.

13 Reserved

14

Motor current phase A
(AN[3])

Short
Float

Phase A current, in amperes.

15

Motor current phase B
(AN[4])

Short
Float

Phase B current, in amperes.

16

Speed command (DV[2])

Long
Float

Speed reference to speed controller,
in counts/second.
