6SN1118-0DH23-0AA1 - Control Board - SIEMENS
Digital control board SIEMENS reference 6SN1118-0DH23-0AA1.
SIMODRIVE 611-D CLOSED-LOOP PLUG-IN PERFORMANCE CONTROL UNIT,2-AXES,FOR DIGITAL DRIVES,FEED+MAIN SPINDLE DRIVES WITH DIRECT MEASURING SYSTEM VOLTAGE SIGNALS
Control board reconditioned and tested under full load (time test) on 611D bench coupled to 1 drive and 1 SIEMENS power supply.
The 1-axis and 2-axis digital control units (for 1PH, 2-axis control only possible with High Performance) are available for motors
1FT6 / 1FK / 1FN1 / 1FN3 / 1FE1 / 1PH / 1PM / 1FM6 / 2SP1.
During the initialization phase (power up or reset), the drive software is downloaded from the SINUMERIK 840D to the control board via the drive bus.
The 1-axis high-performance digital controller can be loaded with the drive software for the FD control or the MSD control. MSD and FD have the same user interface. The card is available in the following versions: Basic version with sinusoidal voltage signals and the possibility of connecting absolute encoders with EnDat interface
In addition, evaluation of a direct position measuring system with sinusoidal voltage signals and the connection of absolute encoders with EnDat interface and SSI interface is possible.
The module is available in three basic versions which differ in the performance of the controller and in the evaluation of the direct position measuring systems:
Basic version with sinusoidal voltage signals and possibility of connection of absolute encoders with EnDat interface In addition, evaluation of two direct measurement systems with sinusoidal voltage signals and connection of absolute encoders with EnDat interface and SSI interface is possible.
Basic version with sinusoidal voltage signals and the possibility of connecting absolute encoders with EnDat interface. In addition with evaluation for 2 direct measurement systems with sinusoidal voltage signals and the possibility of connecting absolute encoders with EnDat interface and SSI interface.
All drive–related settings of the control board can be made as follows:
– Using the SimoCom U parameterizing and startup tool on an external PG/PC
– Using the display and operator control unit on the front panel
– Using PROFIBUS DP (parameter area, PKW area)
- Software and data
The firmware and the user data are saved on a memory module which can be replaced.
The software designation on the memory module refers to the system soft- ware including the initial program loader.
- Terminals and operator control elements
– 2 analog inputs, 2 analog outputs per drive
– 4 digital inputs, 4 digital outputs per drive
– 2 measuring sockets
– POWER–ON RESET pushbutton with LED
– Display and operator unit
- Safe start inhibit
The start inhibit is addressed via terminal 663 and is signaled back using a relay with positively–driven signaling contacts (AS1/AS2). Using the start inhibit, the energy feed from the drive to the motor is interrupted.
When the ”safe start inhibit” function is correctly used, the signaling contacts AS1/AS2 must be included in the line contactor circuit or the EMERGENCY OFF circuit.
When using the ”safe start inhibit” function, it must be ensured that the velocity goes to zero.
The ”SIMODRIVE 611 universal HRS” control board supports the ”Safe standstill” function.
Serial interface (RS232/RS485)
– Optional TERMINAL module,
8 digital inputs and 8 digital outputs for drive A
– Optional PROFIBUS–DP module Expanded functions as of SW 5.1
The following expanded functionality is provided with a new control board for sin/cos 1Vpp encoders:
Higher internal resolution, interpolation factor 2048 (previously 128)
Pulse multiplication is possible (doubling) at the angular incremental en- coder interface for absolute encoders
Pulse multiplication (doubling) and division (1:2, 1:4, 1:8) are possible at the angular incremental encoder interface, also for incremental encoders.
Siemens is an international group of German origin specializing in high technology and present in the sectors of industry, energy and health. It was founded in 1847 by Werner von Siemens.
