Servo Parameters
Chapter 7
7-58
Function
This parameter is only available for analog servo hardware.
This parameter is used to scale the signal sent from the analog servo
interface to the servo amplifier. This signal may range from --10.0000 to
+10.0000 volts. The lower portion of this range is set with the parameter
Analog Servo Neg Voltage. This value must be entered accurately. Use
values attained from drive specifications or testing. This value is used for
calculation of the servo motors continuous rated current which is used later
as a percent of this parameter. Note use the maximum servo acceleration
value if position/velocity loop is chosen as closed by the control (see table
below). If you feel you must limit the analog output voltage to protect
your machine, use the parameter Max Rated Torque.
If the servo loop type is
configured as:
enter the positive voltage that the servo module must send to the
amplifier to:
position loop maintain rapid axis speed in the positive direction
The value entered for this parameter should be below 10 volts. If 10
volts is entered, the control is unable to compensate for any increase
in axis load that may occur at rapid speed.
position/velocity attain maximum servo acceleration in the positive direction. Typically
this is the voltage that is sent to the drive to get the drive to output the
servo motors maximum (peak) rated current.
