6 Programmable Features and Parameters
All PositionServo 940 series drives are configured through one of the interfaces:
RS232, RS485 or Ethernet. The drives have many programmable and configurable
features and parameters. These features and parameters are accessible via a
universal software called MotionView. Please refer to the MotionView 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 the
PositionServo Model 940 drive in the order they appear in the Parameter Tree of
MotionView. Programmable parameters are divided into groups. Each group holds
one or more user’s adjustable parameters.
All 940 series drives can execute a User Program in parallel with motion. Motion can
be specified by variety of sources and in three different modes:
• Torque
• Velocity
• Position
In Torque and Velocity mode Reference can be taken from Analog Input AIN1
or from the User Program by setting a particular variable (digital reference). See
Programmer’s Manual for details on programming. In Position mode, the reference
could be taken from MA/MB master encoder/step and directions inputs (available
in terminal P3) or from trajectory generator. Access to the trajectory generator is
provided through the User Program’s motion statements, MOVEx and MDV. See
Programmer’s Manual for details on programming.
Whether the reference comes from an external device, (AIN1 or MA/MB ) or from the
drives internal variables (digital reference and trajectory generator) will depend on the
parameter settings. Refer to “Parameters” group in MotionView.
6.1 Parameters storage and EPM operation
6.1.1 Parameter’s storage
All settable parameters are stored in the drive’s internal non-volatile memory.
Parameters are saved automatically when they are changed. In addition, parameters
are copied to the EPM memory module located on the drive’s front panel. In the
unlikely event of drive failure, the EPM can be removed and inserted into the
replacement drive, thus making an exact copy of the drive being replaced. This
shortens down time by eliminating the configuration procedure. The EPM can also be
used for replication of the drive’s settings.
6.1.2 EPM operation
When the drive is powered up it first checks for a white EPM in the EPM Port. If the
EPM Port is empty, no further operation is possible until a white EPM is installed into
the EPM Port. The drive will display “
EP-”
” until an EPM is inserted.
If a different color EPM is inserted the drive may appear to function however, some
operations will not be correct and the drive may hang. The White EPM is the only
acceptable EPM for the PositionServo 940 drive. If a white EPM is detected, the
drive compares data in the EPM to that in its internal memory. In order for the drive to
operate, the contents of the drive’s memory and EPM must be the same. Press the
enter button to load the EPM, this will take a moment.
STOP!
If the EPM contains any data from an inverter drive, that data will be
overwritten during this procedure.
