Halt Command

Character: H or h
Decimal: 72 or 104
Hexadecimal: 0x48 or 0x68
Command Value: Unused

Note: A Go command with zero speed is typically a way to stop an axis than using the Halt command. See below for details.

The Halt command starts an immediate deceleration to a stop in closed loop. It uses the previous deceleration rate specified for the axis. This command also disables the integrator and the null update so the integrator does not wind up if the hydraulic pump is turned off or the motor drive disabled.

This command should only be used with PROFIBUS Compact mode communications. Other communication types should use a Go command with a Speed parameter of zero. This will immediately decelerate the axis to a stop. It gives you control over the deceleration rate (Decel parameter) and the integrator mode (Mode paramter). When using the Go command with zero speed, the specified position is not important as long as it is within the extend and retract limits.

If an event sequence is in progress when the Halt command is issued, the event sequence will be stopped. Compare this command with the Disable Drive Output and Quit Events commands.
