Screen 2: I/O Settings Configuration Screen

The I/O Settings screen may be accessed by clicking View > IO Settings on the menu bar. This screen is used to configure the Input Clock type, the filtering and the Active High/Low State of the Enable Input.

Input Clock Type

The Input Clock Type translates the specified pulse source that the motor will use as a reference for establishing stepping resolution based on the frequency.

The three clock types supported are:

1.Step/Direction

2.Quadrature

3.Up/Down

The Clock types are covered in detail in Section 2.2: Logic Interface and Connection.

Input Clock Filter

The clock inputs may also be filtered using the Clock IOF pull down of the IMS SPI Motor Interface. The filter range is from 50 nS (10 MHz) to 12.9 µSec. (38.8 kHz). Table 2.4.3 shows the filter settings.

Input Clock Filter Settings

Min. Pulse	Cutoff Frequency
50 nS	10 MHz
150 nS	3.3 MHz
200 nS	2.5 MHz
300 nS	1.67 MHz
500 nS	1.0 MHz
900 nS	555 kHz
1.7 ∝S	294.1 kHz
3.3 ∝S	151 kHz
6.5 ∝S	76.9 kHz
12.9 ∝S	38.8 kHz

Enable Active High/Low

The parameter sets the Enable Input to be Active when High (Default, Disconnected) or Active when Low.

Warning Temperature

The parameter sets the temperature at which a TW, or temperature warning fault code will be generated. In the warning condition the MForce PowerDrive will continue to operate as normal. The thermal shutdown is +85°C.
