Figure 2.3.7: SPI Motor Interface Motion Settings Screen
The IMS SPI Motor Interface Software opens by default to the Motion Settings Screen shown on the left. There are six basic parameters that may be set here:
1.MSEL: Microstep Resolution Select.
2.HCDT: Holding Current Delay Time.
3.MRC: Motor Run Current
4.Motor Holding Current
5.User ID:
6.Direction Override: Allows the user to set the CW/CCW direction of the motor in relation to the Direction Input from the SPI Motor Interface.
MSEL (Microstep Resolution Selection)
The MDriveAC Plus Microstepping features 20 microstep resolutions. This setting specifies the number of microsteps per step the motor will move.
The MDriveAC Plus MicroDrive uses a 200 step (1.8°) stepping motor which at the highest (default) resolution of 256 will yield 51,200 steps per revolution of the motor shaft.
See Table 2.3.2 for available Microstep Resolutions.
