5.21.2 - Explanation of parameters in menu 20
20.01 : Emergency run selection
Adjustment range : No (0) or Yes (1)
Factory setting : No (0)
Format: 8 bits
No (0):
Normal operation.
Yes (1):
Emergency run mode is enabled.
Note:
If 20.01 is at Yes, digital inputs are forced to positive logic
( 08.29 = Positive).
When 20.01 is at Yes (1), and the STO1 and STO2 inputs are
closed, the drive operates in emergency run mode.
It is advisable to use an inverted digital input as source for
20.01 so that in the event of accidental opening 20.01
switches to 1 and activates emergency operation.
In emergency run mode:
- The drive starts in forward only at the speed selected by
parameters 20.03 and 20.04
- The run/stop commands defined by parameter 06.43 are
ignored.
- The drive enable parameter 06.15 is ignored.
- The power diagnostic sequences are
not performed.
- The drive ignores all commands from the keypad.
- Trips relating to the software are disabled, but alarm 10 is
active to indicate their presence.
- The other trips are reset
automatically, independently of 10.80 (no limiting by 10.34 ).
- Flying restart mode is activated independently of 06.09 and
remains enabled for future operations.
- Autotuning is not performed on the run command.
20.02 : Trip inhibition
Adjustment range: No (0) or Yes (1)
Factory setting: No (0)
Format: 8 bits
No (0):
Normal operation
Yes (1):
Software trips (see list in 20.15 ) are not taken into account but
alarm 10 is active to indicate their presence. Other trips are
reset automatically independently of 10.80 (no limiting by
10.34 )
20.03 : Emergency run remote/local reference
Adjustment range : Remote (menu 1) (0) or
Local (menu 20) (1)
Factory setting : Remote (menu 1) (0)
Format: 8 bits
Remote (menu 1) (0):
The drive speed reference is equal to the reference for item B in
menu 1. If a 4-20 mA trip is detected on one of analog inputs 2
or 3, the speed reference will be determined by 20.04 .
Local (menu 20) (1):
The drive speed reference is defined by parameter 20.05 if
20.04 is at 0 or by parameter 20.06 if 20.04 is at 1.
20.04 : Emergency run local speed
reference selector
Adjustment range: Ref 1 ( 20.05 ) (0) or Ref 2 ( 20.06 ) (1)
Factory setting: Ref 1 ( 20.05 ) (0)
Format: 8 bits
Ref. 1 ( 20.05 ) (0):
The emergency run mode speed reference equals 20.05 .
Ref. 2 (
20.06
)(1):
In emergency run mode speed reference equals 20.06 .
CAUTION:
The
07.28
and
07.29
parameters «4/20 mA current loop»
are always displayed even when AI2 is set to «4/20 mA
without detection» (factory setting).
If input AI2 is not used, set 07.11 to 0/20 mA.
20.05 : Emergency run speed reference 1
Adjustment range: ± 01.06
Factory setting: 0.00 rpm
Format: 32 bits
Emergency run speed reference.
20.06 : Emergency run speed reference 2
Adjustment range: ± 01.06
Factory setting: 0.00 rpm
Format: 32 bits
Emergency run speed reference.
20.09 : Emergency run speed reference
Adjustment range: ± 01.06
Format: 32 bits
Emergency run speed reference taken into account.
• keypad control (
06.43
= LCD keypad) is not
suitable for emergency run mode.
20.10 to 20.14 : Not used
