PARAMETER AND VARIABLE DESCRIPTIONS
1557-UM050F-EN-P – June 2013
Automatic Restart Delay [Auto restart dly]
Linear number:
3
Minimum value
0.000 sec
Maximum value:
10.000 sec
Default value:
0.000 sec
This parameter specifies the time interval after a line voltage outage during which the drive will automatically
restart if the line voltage is restored, assuming that the drive was running at the time of the outage. The drive
will restart only if control power is maintained during the outage.
Test Mode [Test mode]
Linear number:
4
Minimum value
0
Maximum value:
4
Default value:
0
This parameter specifies the drive test mode. It is not saved and is set to zero at power up. If this parameter is
changed when the drive is running, the change will not take effect until the drive is stopped.
0
normal operating mode
1
gate test mode (medium voltage off)
2
dc current test mode
3
system test mode
4
open circuit test mode
Refer to Chapter 5 for a description of the test modes.
Speed Command Select 0 [Spd cmd select 0
]
Linear number:
6
Minimum value
1
Maximum value:
15
Default value:
1
This parameter specifies the speed command that is selected when parameter Speed Command Select has a
value of 1. The 11 possible sources of speed command that can be selected by this parameter are:
1
Speed Command 0 (analog input 1L)
2
Preset Speed Command 1
3
Preset Speed Command 2
4-8
Preset Speed Command 3
9
Speed Command 8 (analog input 1M)
10
SCANport adapter 1 (Communications Processor board Port 1)
11
SCANport adapter 2 (Communications Processor board Port 2)
12
SCANport adapter 3 (not used)
13
SCANport adapter 4 (not used)
14
SCANport adapter 5 (not used)
15 SCANport adapter 6 (1336-GM1 RI/O adapter)
This parameter was added in Rev 4.62/5.11 and replaces parameter Default Speed Command Select.
Speed Command Select 8 [Spd cmd select 8
]
Linear number:
9
Minimum value
1
Maximum value:
15
Default value:
9
This parameter specifies the speed command that is selected when parameter Speed Command Select has a
value of 9. The possible sources of speed command that can be selected by this parameter are the same as
parameter Speed Command Select 0.
This parameter was added in Rev 4.62/5.11.
