Function Description

2.1.1.9 Function Description
2.1.1.9.1

Operating Modes and Drive Functions

The operating modes of the DC Drive Controller permit positive and negative
movement with position feedback and automatically approach a setpoint
position.
When positioning automatically, the positioning accuracy can be optimized
via optional parameters (Prestop, Retry, etc.).
Other parameters for target window size, stop interval for reversion of rotating
direction or compensation of gearbox clearance adapt the system to the
mechanics.
2.1.1.9.2

Preset Functions

Two different preset functions can be used to reference the drive.
The value can be specified via parameter; after enabling the preset input, this
value is assigned to its position when approaching the reference cam.
Afterward, the drive is stopped.
A second option is using the control to assign the setpoint value to the actual
position.
Notification of preset function execution is returned via terminal status; the bit
'Reference_OK' goes to logic 1. During running operation, this bit is reset to
logic 0 by one of the following events:
• restart a preset motion
• failure of field-sided 24 V
• overflow or underflow of the actual position counter.
