SIMOTRAS HD Operating Instructions
9.3 Commands for switch on, shutdown and disabling of the firing
pulses
NOTE
The commands described here for switch on, shutdown and disabling of the firing pulses are part
of the command specified using “control word 1” (see Section 8, function diagram Sheet G180)
The Switch on/Shutdown (ON/OFF1)” and “enable operation” commands are controlled by
default by the crane control contained in the SIMOTRAS HD or by the external safety monitoring
system (“mechanical stop”) (see Section 6.1).
The commands “Disconnect voltage (OFF2)” and “Fast stop (OFF3)” are not used in standard
applications.
9.3.1 Switch-on / shutdown (ON / OFF1): terminal 37 - control word 1, bit 0
The “Shutdown” command causes the controlled braking of the drive unit to a standstill, disabling of
the firing pulse and dropout of any line contactor present if controlled by binector B0124.
The switch on command (bit 0 in control word 1) is formed from the logical operations:
-
ON / OFF1 from the crane control (see Section 6.1), applied by P654=9360
-
"Switch-on / Shutdown" signal from terminal 37 (ext. “electrical stop”)
-
Bit 0 on the connector selected via P648
-
Switch on commands from INCH and CRAWL
See also Section 8 function diagrams, Sheets G130 and G180.
Operating modes:
U617 = 0: Signal from terminal 37 not active, ON command comes from the crane control
U617 = 1: AND operation between terminal 37 and ON from the crane control (ON only if both are
log. 1). External "Electrical stop" via terminal 37
P648 = 9: The control bits in control word 1 are input bit-serially.
Bit 0 on the connector selected via P648 is not active.
The ON command is created depending on U617 (see above).
P648
≠
9: The connector selected via P648 is used as control word 1.
The ON command is created depending on U617 (see above). In addition, the signal
generated there is ANDed with bit 0 of the connector selected via P648 (ON only if both
signals are log. "1").
P445 = 0: The ON command is level-triggered.
The ON command is created depending on U617 and P648 (see above):
1=ON, 0=OFF
P445 = 1: The ON command is edge-triggered.
The ON command created depending on U617 is saved at the 0
→ 1 transition. The
binector selected in P444 must be in the log. "1" state. The memory and thus the OFF
command is reset when this binector switches to the log. "0" state.
