Parameters

Reset 1 Input Internal Parameter, Read-only, Boolean (signed 16-bit integer)

Stepper Status Monitor - Reset 1 Input

The actual, current digital state of the reset input at smarty terminal T7.

Only valid with dwOption-37


0 = Low
1 = High
Reset 2 Input Internal Parameter, Read-only, Boolean (signed 16-bit integer)

Stepper Status Monitor - Reset 2 Input

The actual, current digital state of the reset input at smarty terminal T8.

Only valid with dwOption-37


0 = Low
1 = High
Count 1 Internal Parameter, Read-only, Analog (unsigned 16-bit integer)
0 to 65535

Stepper Status Monitor - Count 1

The actual number of pulses produced at smarty terminal T3.

The count automatically resets to zero at power-up and after incrementing past the maximum value, 65535.

This count is not affected by position reset events.


Count 2 Internal Parameter, Read-only, Analog (unsigned 16-bit integer)
0 to 65535

Stepper Status Monitor - Count 2

The actual number of pulses produced at smarty terminal T5.

The count automatically resets to zero at power-up and after incrementing past the maximum value, 65535.

This count is not affected by position reset events.


Output 1 Hz Internal Parameter, Read-only, Analog (signed 16-bit integer)
-32767 Hz to 32767 Hz

Stepper Status Monitor - Output 1 Hz

The actual, current frequency in Hertz of the Stepper 1 output at smarty terminal T3.

-32767 = Under-Range
32767 = Over-Range
Output 1 kHz Internal Parameter, Read-only, Analog (signed 16-bit integer)
-500.0 kHz to 500.0 kHz

Stepper Status Monitor - Output 1 kHz

The actual, current frequency in kilohertz of the Stepper 1 output at smarty terminal T3.

Output 2 Hz Internal Parameter, Read-only, Analog (signed 16-bit integer)
-32767 Hz to 32767 Hz

Stepper Status Monitor - Output 2 Hz

The actual, current frequency in Hertz of the Stepper 2 output at smarty terminal T5.

-32767 = Under-Range
32767 = Over-Range
Output 2 kHz Internal Parameter, Read-only, Analog (signed 16-bit integer)
-500.0 kHz to 500.0 kHz

Stepper Status Monitor - Output 2 kHz

The actual, current frequency in kilohertz of the Stepper 2 output at smarty terminal T5.
