6.10 Faults Group
Faults Group loads fault history from the drive. New faults replace oldest faults in a
circular manner. In any case fault # 0 is the most recent fault. To clear faults history
from the drive’s memory click on “Reset Fault history” button. Each fault has its code
and explanation of the fault. See section 7.3 for details on faults.
6.11 Tools Group
6.11.1 Run Panel
Run Panel is active in velocity mode only. It replicates an analog potentiometer as if it
would be connected to analog reference input. Velocity Scale parameter in Parameter
Group set the scale of this “potentiometer” just the same way it sets it for analog input.
There is a check box “Enable Reference sweep” which makes reference invert with
period set by parameter (on run panel) “Sweep Time”. This feature of the run panel
allows you to create “Square wave” reference with adjustable period (“Sweep Time”)
and magnitude (Reference Slider) for easy tuning.
6.11.2 Drive monitor
Drive monitor shows you the motor hall sensor states and actual motor encoder
counts. This tool is useful when troubleshooting the motor’s encoder connections.
6.11.3 Oscilloscope tool
Oscilloscope tool gives real time representation of different signals inside the
SimpleServo drive and is helpful when debugging and tuning drives. Operation of
oscilloscope tool described in MotionView software’s User’s Manual. Below given the
list of the signals you can observe with oscilloscope tool:
Phase Current (RMS): Motor phase current
Phase Current (Peak):
Motor peak current
Iq Current: Measures the motor Iq (torque producing) current
Motor Velocity: Actual motor speed in RPM
Commanded Velocity:
Desired motor speed in RPM (velocity mode only)
Velocity Error: Difference in RPM between actual and commanded
motor speed
Position Error: Difference between actual and commanded position
(Step & Direction mode only)
Bus voltage:
DC bus voltage
Analog input: Voltage at drive’s analog input
