ABB DO801 3BSE020510R1 Digital Output 24V 16 ch

This mode is the same as the Velocity Mode Analog Command except that the command input comes from the Incremental Command inputs on J2-17 through J2-20. The frequency on these input terminals is the variable DigitalCmdFreq and is substituted for the AnalogIn input to the CmdGain scaling. The units on CmdGain are kRPM/kHz. Motor Velocity[kRPM] = EncFreq[kHz]*CmdGain[kRPM/kHz]

Velocity Mode - Serial Command

 This mode is the same as the Velocity Mode Analog Command except that the command input is the value of Velocity Command (VelCmd) set over the serial port. Note that VelCmd is a non-volatile parameter and when the PC830 servo powers up in this mode the initial value of the velocity command is this non-volatile value. Changing VelCmd over the serial port then sets a new volatile velocity command. Changing the non-volatile velocity command requires the additional step of issuing the NVSave command.

Torque Mode - Analog Command 

This mode allows the differential analog voltage between terminals J2-1 and J2-2 to set the motor’s current. Since torque command = Current command (Icmd) *Kteff, controlling current is equivalent to controlling torque. The analog input directly controls motor shaft torque. The output current amplitude in amps per input volt, is set by the CmdGain parameter directly in Amp/V and should be set by the user to the desired value. Procedure 1. Select the Torque Mode - Analog Command from the Mode of Operation dropdown list box. 2. Set CmdGain to the desired value.
