• Gives the command velocity which is generated in the Servo Drive, in units of r/min.
• Gives the velocity command value which is generated in the position control of the Servo Drive.
• The displayed value may have an error due to the unit conversion from [r/min] to [command unit/s].
• Mirror object of 60FA hex
• Gives the deviation between the command velocity to the feedback control and the present velocity.
Gives the velocity detection value.
• Gives the present velocity in units of command/s.
• Mirror object of 606C hex
• Gives the present motor velocity in units of r/min.
• Gives the motor acceleration.
