83h Description: (Execute Speed) Commands the unit to execute the speed commanded in (#82) above.

84h Description: (Set and Execute Speed) Commands the unit to set a new speed (or ratio) and change to it immediately without waiting for an execution command.

85h Description: (Read Parameter)

Commands the unit to send a specified current parameter setting.

86h Description: (Write Parameter) Commands the unit to change a specific parameter to a new value.

87h Description: (Read Analog Input) Commands the unit to send the value of an analog input.

88h Description: (Read Analog Output) Commands the unit to send the value of an analog output.

89h Description: (Write Analog Output) Commands the unit to put a specific value out on one of the analog outputs.

8Ah Description: (Read Digital Input) Commands the unit to send the status of a digital input.

8Bh Description: (Read Digital Output) Commands the unit to send the status of a digital output.

8Ch Description: (Set Digital Output) Commands the unit to turn on or off a specific digital output.

8Dh Description: (Set Operational Mode) Allows setting run, stop, preset, reverse commands via comm link rather than through the hardwired inputs.

8Eh Description: (Read Operational Mode) Allows reading the status of all command conditions.

8Fh Description: (Application Mode)
