Command Source

The Command Source screen allows you to configure a variety of settings depending on which mode the servo drive is in. Different screens are available for Speed (S), Position (PT), Torque (T), and Combination (PT/S) modes.

• Note: When running the drive in PR mode the Command Source menu option will disappear entirely. Command Source is not applicable when in PR Mode. The relevant command source information is found in the PR Mode Setting window.

On each screen you can load the current settings by clicking Read All Parameters.

Parameter data can be adjusted by selecting the appropriate radio button or drop-down menu item. To update multiple parameters, click Write All Parameters to copy the parameter values to the servo. To update just the parameters bounded by the blue box, click Write Selected Item(s).

Command Source - PT Mode

The Command Source screen in PT Mode allows you to adjust the external pulse input type, filter type, and pulse filter width.

SureServo2 - PT Mode

Option	Function
P1.000 External Pulse Input Type	Select one of the six radio buttons to choose either positive or negative logic with AB phase pulse, CW +CCW pulse, or pulse + symbol inputs.
Filter Type	Select either low frequency or high frequency pulse commands
Pulse Filter Width	Select a pulse filter width from 125Hz to 5mHz. Choose 0 to bypass.

Command Source - S Mode

The Command Source screen in S and Sz Mode allows you to adjust the speed registers and DI assignments for SPD0 and SPD1.

SureServo2 - Speed Mode

Option	Function
Limit Registers	P1.009, P1.010, and P1.011 are the preset speed values (in .1rpm) that can be commanded by digital inputs SPD0 and SPD1. Example: if SPD0 = ON and SPD1=OFF, the diagram shows that the motor will be commanded to run at the speed set in P1.010 Speed Register2. In Sz Mode, if both SPD0 and SPD1 are OFF, the motor will be commanded to zero speed (that's what the "z" stands for). In S Mode, if both SPD0 and SPD1 are OFF, the motor will be commanded to the speed set by the analog input V-REF.
SPD0	Select a DI function from the drop down for SPD0 and then select Normally Open (A) or Normally Closed (B) functionality.
SPD1	Select a DI function from the drop down for SPD1 and then select Normally Open (A) or Normally Closed (B) functionality.

Command Source - T Mode

The Command Source screen in T and Tz Mode allows you to adjust the torque registers and DI assignments for TCM0 and TCM1.

Option	Function
Limit Registers	P1.012, P1.013, and P1.014 control limit registers 1, 2, and 3. These set the torque limit in forward and reverse directions as a percentage. The range is -400 to 400, but any value entered will provide the same limit for both negative and positive directions. For example, a value of -50 will provide a limit of -50% in reverse and +50% forward. A value of 50 will ALSO provide a limit of -50% in reverse and +50% forward. In Tz Mode, if both TCM0 and TCM1 are OFF, the motor will be commanded to zero torque (that's what the "z" stands for). In T Mode, if both SPD0 and SPD1 are OFF, the motor will be commanded to the torque set by the analog input T-REF.
TCM0	Select a DI function from the drop down for TCM0 and then select Normally Open (A) or Normally Closed (B) functionality.
TCM1	Select a DI function from the drop down for TCM1 and then select Normally Open (A) or Normally Closed (B) functionality.

Command Source - PT/S Mode

The Command Source screen in PT/S Mode gives access to both the Position Mode tab and Speed Mode tab as described previously.
