6 SS500/600 Programmable Features and
Parameters
All SimpleServo drives are SetUp through serial or Ethernet( SSi drives only) interface. Drives have
many programmable and configurable features and parameters. These features and parameters are
accessible via universal software called MotionView. Please Refer to MotionView User’s Manual for
details on how to make a connection to the drive and change parameter values.
This chapter covers programmable features and parameters specific to SimpleServo drives in the
order they appear in the left tree of the MotionView. Programmable parameters are divided into
groups. Each group holds one or more user’s adjustable parameters.
6.1 Motor Group
Motor group shows currently selected motor. You can click “CLICK HERE TO CHANGE” to view
selected motor parameters or select new motor. Please refer to Section 5.7 for details on how to select
motor.
6.2 Parameters Group
6.2.1 Drive operating modes
The SimpleServo has 3 operating modes: Torque, Velocity or Step & Direction.
Depending on what servo system you want to build you will choose on of these modes.
For Torque and Velocity modes drive will accept an analog input voltage on the IN+ and IN- pins of
TB502 or TB506. This voltage is used to provide torque or speed reference.
For Step and direction mode drive will accept step and direction logic signals or quadrature pulse
trains. Depending on the selected mode, some parameters are active while others are disabled. Refer
to Table 14 to determine active parameters for mode selected.
• Velocity mode
In velocity mode, the servo control regulates motor shaft speed (velocity) proportional to
analog input voltage.
Target speed ( set speed ) is calculated using formula:
Set Velocity (RPM) = Vinput (Volt) X Vscale (RPM/Volt) ,
where:
Vinput- voltage at analog input
Vscale - velocity scale factor (input sensitivity) set by Analog input(Velocity scale)
parameter.
• Torque mode
In torque mode, the SimpleServo control provides a current output proportional to the analog
input signal, up to the maximum current output rating of the drive. Set Current (current the
drive will try to provide) is calculated using formula:
Set Current(A) = Vinput(Volt) X Iscale (A/Volt) ,
where:
Vinput - voltage at analog input
Vscale - current scale factor (input sensitivity) set by Analog input (Current Scale)
parameter.
