7 SSi10XX Programmable Features and Parameters
In this chapter, we will cover programmable features and parameters specific for SSi drives in order
they appear in left tree of the MotionView.
7.1 Motor folder
This folder contains action button to choose particular motor. The rest of the fields contain information
about selected motor. See Section 5.7 for detailed information how to set up motor.
7.2 Parameters
7.2.1 Drive mode
SSi drives always operate in primary positioning mode, however two different configurations are
available:
• PIVFF mode. P(roportional)I(intgral)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 both are active in this mode.
7.2.2 Current Limit
The Current Limit setting determines the nominal current, in Amps RMS per phase.
7.2.3 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.
7.2.4 Autoboot
If this option is selected after Power Up SSi will start execution of the user program currently stored in
drive’s memory. Otherwise program must be started manually via MotionView software or via Host
Interface.
7.2.5 Feedback loss detection
When this option is enabled, the SSi will detect feedback loss, disable, and then generate fault.
7.2.6 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 another control tasks, PPP is recommended.
