4 Control Units
4.2 "SIMODRIVE 611 universal HRS" control board
4-92
S
Settings
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)
S
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.
S
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
S
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.
Caution
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.
Detailed information about the "safe standstill" function is provided in Chap-
ter 8.5.
S
Serial interface (RS232/RS485)
S
Option modules
– Optional TERMINAL module,
8 digital inputs and 8 digital outputs for drive A
– Optional PROFIBUS–DP module
S
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
