Operating Enable: Terminal 38 - Control Word 1, Bit 3 - Siemens SIMOTRAS 6SG7050 Operating Instructions Manual

Operating enable: terminal 38 - control word 1, bit 3

The command "No enable operation" causes the fastest possible disabling of the firing pulses, but no
drop out of any line contactor present, if controlled using binector B0124.
The enable operation command (bit 3 control word 1) is formed from the logical operations :
Enable from the crane control (see Section 6.1), applied via P661=9382 and
-
"Enable operation" signal from terminal 38 with crane drive control as described in Section 6 or
-
Bit 3 on the connector selected via P648
-
See Section 8, Sheet G180.
Operating modes:
U618 = 0: Signal from terminal 38 not active, enable comes from the crane control
U618 = 1: AND operation between terminal 38 and enable from the crane control (enable only if both
are log. 1).
P648 = 9: The control bits in control word 1 are input bit-serially.
Bit 3 on the connector selected via P648 is not active.
The operating enable command is generated from the AND operation between the enable
signal from terminal 38 and the binector selected in P661 (see Section 8, Sheet G180).
P648 ≠ 9:
The connector selected via P648 is used as control word 1. Bit 3 on this connector is
ANDed with the enable operation signal as for the log. AND signal with P648=9.
To ensure that the "Operating enable" function can be activated, the conditions defined in the following
diagram must be fulfilled:
Operating enable (from te.38)
Sequence of operations for enabling operation (if a switch-on command is applied):
1. Enter the "Enable operation" command
2. With a positive brake release time (P087), output a "Release holding or operating
brake" signal (binector B0250 = 1) and wait for P087 to run down in operating state o1.0,
with a negative brake release time (P087 negative), go to step 3 immediately, brake
remains closed (binector B0250 = 0)
3. Ramp-function generator, n and I controllers are enabled
4. Converter reaches operating state I, II or – –
5. When a negative brake release time (P087) has run down, output signal "Release holding or
operating brake" (binector B0250 = 1).
Sequence of operations for cancellation of operating enable:
1. Cancel "Enable operation" command
2. Disable ramp-function generator, n and I controllers
3. Enter I
set
4. The pulses are disabled when I = 0
5. Output signal "Close operating brake" (binector B0250 = 0, when P080 = 2)
6. The converter reaches operating state 0.10 or higher
7. Drive coasts to a standstill (or is braked by the operating brake)
8. When n < n
B0250, when P080 = 1)
