Lenze PMSS1000 Simple Servo - Manual (Page 5)

Indexer-Programmer-Manual.pdf REV 1.3
Getting started with SSi
Before SSi can execute motion program it has to be properly installed and configured. First time users are
encouraged to read through the appropriate sections in this manual and in SimpleServo User's Manual for
proper hardware installation and configuration.SSi programmable features and parameters
SSi drives have a number of features and parameters which can be programmed via MotionView
Software. Below is a list of programmable features and parameters specific for SSi drives in order they
appear in left tree of the MotionView. Please refer to User's Manual for details on these parameters.
Motor folder
This folder contains action button to choose particular motor. The rest of the fields contain information
about selected motor. See MotionView Help on detailed information how to setup motor.
Parameters
• Drive mode
PIVFF mode. P(roportional) I(ntgral) V(elocity F(eed) F(orward) regulator configuration. This
mode using tunable position loop. Velocity feedback is used as dumping term and adjusted
automatically. Velocity feed forward gain is adjustable.
• P+V mode. P(osition) +V(elocity) regulator configuration. This mode is generally slower than
PIVFF and used with lower performance mechanics. Regulator consists of outer position loop
followed by independent velocity loop followed by current loop. Position and velocity loop gains
are in tacked in this mode.
• Current Limit
Sets RMS motor current limit. Settings per phase Amps RMS
• Peak Current Limit
Sets RMS per phase peak current limit. This current limit is allowed for 2 Seconds. After that it will
be folded back to the level that is set by Current limit parameter.
• Autoboot
If this option is selected after Power Up SSi will start execution of the user program. Otherwise
the program must be started manually via MotionView software or via Host Interface.
Warning!
• Hazard of unexpected motor starting! When using the MotionView software, or otherwise
operating the SSi drive over RS-232/485 or Ethernet, the motor may start unexpectedly,
which may result in damage to equipment and/or injury to personnel. Make sure the
equipment is free to operate in this manner, and that all guards and covers are in place to
protect personnel.
• Feedback loss detection
When this option is enabled SSI will detect feedback loss, then consequently disable, and
generate fault.
• RS485 configuration
Switches between different protocols can be used over RS485 interface. In normal mode, PPP
protocol (described in Host Interface manual) is used. "Modbus slave" is another alternative
protocol can be used to communicate with SSI drive. Modbus primarily supported for compatibility
with industry standard operator interfaces and terminals. For all other control tasks, PPP is
recommended.
