SK 530E
frequency inverters are voltage source frequency inverters with fully digital microprocessor
technology designed to control the speed of three-phase current motors.
In combination with an
incremental encoder
or
absolute encoder
, the standard components become a highly
accurate positioning drive:
•
The frequency inverter contains 15 programmable absolute positions.
•
Position is maintained even through strong load fluctuations thanks to the position control.
•
Time optimised and secure travel to the aim thanks to path calculations.
•
In addition to travelling to absolute positions, up to 4 incremental settings ( so-called position
increments) can be saved in the frequency inverter.
•
Required positions can also be transmitted via a field bus interface.
•
The positioning function is available in the SK 530E as a function extension.
The parameters (P6xx) required for positioning are included in the existing inverter menu structure as an additional
menu group (Positioning)
The position setpoint specification can be set via the existing digital inputs, the Bus IO In bits or via the USS
protocol or another field bus system.
Conversion between speed control and position control (positioning) is possible by switching the parameter sets.
Synchronous functionality
between a master and one or more slave drives is possible via the integrated CAN
Bus or the RS485 interface.
A
rotary axis function
(
modulo-axes
) for turntables and similar applications is also available. This controls a
path-optimised endless axis, depending on the position required the drive rotates left or right.
NOTE :
This description (BU 0510) only contains those functions and parameters specific to and relevant for the positioning
functions. All standard functions and parameters can be found in the manual (BU 0500) accompanying the
frequency inverter.
Due to
software updates
, it is possible that the parameters described here may vary from those in your device.
You must ensure therefore that both the current NordCon version and the version of your parameter box are
updated to the latest software version. In case of doubt, contact your local NORD representative.
