7-4
Hardware - SIMADYN D
Edition 03.2001
A socket for a 28 pin EPLD device (ALTERA) is provided on the module for
copy-protecting the user program („Hardlock-PAL“).
Using a special function block, this EPLD block can be checked and the
program execution stopped if it has the incorrect code or no code.
Further information on request.
7.2.2 Mechanical design, terminals
•
The T400 can be used at slot 2 in the MASTER DRIVES electronics box
(outer right!). The PROFIBUS-DP interface (CB1) or CAN bus (CB2) can
be used at slot 3.
The connection to the baseboard at slot 1 and to the expansion board
("COMBOARD") at slot 3 is established via two 64-pin plug connectors.
•
The PC board is 100 mm * 233.35 mm. The maximum component height
above the PC board is 14 mm.
•
All of the input and output terminals are located at the front of the
module. MINI-COMBICON plug connectors from the Phönix company are
used.
•
55 terminals
(five blocks of 11) are located at the foremost edge of the
module.
•
Several terminals are assigned twice as a result of the restricted space.
The actual function is selected using a switch or is configured.
•
Operation
without fan is possible
for a 55°C ambient temperature!.
•
The backplane bus wiring in the
SRT400
technology box is designed so
that two T400 can be used. In this case, connector X2 (below) of the
lefthand slot is connected with connector X1 (top) of the righthand slot.
7.2.3 Incremental encoder with coarse- and fine-pulse evaluation
•
2 incremental encoder inputs, with tracks A, B, and zero pulse of which
−
encoder 1 for HTL signal level
−
encoder 2 for either
HTL or differential signals (RS422);
•
The pulses for encoder 1 (tracks A, B, zero pulse) can be optionally
retrieved from the BASE BOARD via the
backplane bus
(„incremental
encoder simulation“ of the CUx; as TTL signal level).
The pulse source is selected by configuring the speed actual value block
NAV.
•
Max. input frequency 1MHz
•
Selectable, direction of rotation-dependent evaluation of the zero pulses
