3.1. Overview
Inputs/outputs
2 analog outputs
5 analog inputs
2 binary outputs
8 binary inputs
of which 4 binary inputs can be used to call interrupt tasks (50 µs response time)
4 bi-directional binary inputs or outputs
2 incremental encoder inputs with zero pulse
- encoder 1 for HTL (15V) encoder
Encoder pulses of an encoder connected to a SIMOVERT MASTERDRIVES SC/VC which are fed
via the backplane bus to the T400 can also be evaluated. This means it is also possible to use a
TTL/RS422 encoder. The pulse encoder simulation via the backplane bus of the SIMOVERT
MASTERDRIVES MC can also be used.
- encoder 2 for HTL (15V)- or TTL/RS422 encoder (5V)
For each incremental encoder, a coarse pulse input to suppress the zero pulse, the coarse pulse input
(simultaneously) can also be used as binary input.
The inputs/outputs are not electrically isolated
2 absolute value encoders with SSI- or EnDat protocol (RS485) for positioning applications
Note: When using absolute value encoder 2, serial interface 2 (peer, USS) cannot be used, as the
same terminals are used for the two applications!
Serial interface 1 with RS232 or RS485 data transfer format;
The protocol can be selected using a switch on the module:
Service protocol DUST1
for start-up (CFC test mode, service IBS (start-up), TELEMASTER) and downloading programs
with a 19.2 kbit/s baud rate at the RS232 interface
USS protocol,
2 wire, with selectable RS232 or RS485 data transfer format;
max. baud rates, 38.4 kbit/s;
can be configured as slave for parameterization with OP1S (from OP1S, version V2.2),
or as master for the OP2 operator panel connection
Serial interface 2
with RS485 data transfer format, selectable baud rates of: 9.6; 19.2; 38.4; 93.75 and 187.5 kbit/s;
the required protocol is selected by appropriately configuring the function block:
Peer-to-peer
for fast process coupling, 4 wire
USS protocol (USS bus),
can be configured as slave for parameterization with SIMOVIS (2- or 4 wire),
as master for OP2 operator panel connection (2 wire) or to control drive converters;
max. baud rates, 38.4 kbit/s;
Low deadtimes can be achieved as a result of synchronization:
Synchronization of the T400 on the basic drive converter modules (CUx) or second T400
T400 supplies synchronizing signals for other modules (CUx, CBx or second T400)
Other features
•
Lowest sampling time is 0.1 ms, 0.8 ms is the typical sampling time for a control loop
•
As a result of the floating point arithmetic, not only is a high accuracy achieved, but configuring is also
simplified as normalization and value range limits are eliminated
•
Operation without fan
•
3 LEDs for operating status displays
•
Hardlock-PAL: Plug-in socket for 28-pin EPLD device for copy protection of the user program
•
Soldered-in flash memory (2 Mbyte) for the program code (compressed), which is downloaded from the PC
via the serial interface; no plug-in memory module is used!
•
4 Mbyte DRAM as working memory for programs and data,
•
32 Kbyte permanent change memory
•
NOVRAM for data save at voltage-off for up to 10 configurable values (real type)
•
Cache memory: 4 Kbyte program, 4 Kbyte data
•
Clock cycle (external/internal): 32/32 MHz
