Rockwell Automation 1557 MEDIUM VOLTAGE AC DRIVE - Manual (Page 97)

PARAMETER AND VARIABLE DESCRIPTIONS 6-41
1557-UM050F-EN-P – June 2013
Pass Code [Pass code]
Linear number:
262
Minimum value: 0
Maximum value: 65535
Analog Output Scaling: N/A
This variable is the encoded value of the terminal pass number. If the terminal pass number is lost or
corrupted, the value of the pass number can be determined from the encoded value by consulting the factory.
19 Speed Command Variables
Speed Command 0 [Speed command 0]
Linear number:
273
Minimum value: -100.0 Hz
Maximum value: 100.0 Hz
Analog Output Scaling: 1.0 V = 12.8 Hz
This variable is the value of analog speed command 0 from analog input 1L.
Speed Command 8 [Speed command 8]
Linear number:
274
Minimum value: -100.0 Hz
Maximum value: 100.0 Hz
Analog Output Scaling: 1.0 V = 12.8 Hz
This variable is the value of analog speed command 8 from analog input 1M.
Speed Command 9 [Speed command 9]
Linear number:
275
Minimum value: -100.0 Hz
Maximum value: 100.0 Hz
Analog Output Scaling: 1.0 V = 12.8 Hz
This variable is the value of the digital speed command from the selected SCANport adapter. Since the inputs
from all SCANport adapters are multiplexed through this one variable, only the input from the selected adapter
is visible.
Speed Command Input [Speed command in]
Linear number:
276
Minimum value: -100.0 Hz
Maximum value: 100.0 Hz
Analog Output Scaling: 1.0 V = 12.8 Hz
This variable is the value of the selected speed command input. It is valid whether the drive is running or not.
Speed Command [Speed command]
Linear number:
277
Minimum value: -100.0 Hz
Maximum value: 100.0 Hz
Analog Output Scaling: 1.0 V = 12.8 Hz
This variable is the drive speed command, which is the input to the speed ramp. It is set to zero when the drive
is not running.
Speed Reference [Speed reference]
Linear number:
278
Minimum value: -100.0 Hz
Maximum value: 100.0 Hz
Analog Output Scaling: 1.0 V = 12.8 Hz
This variable is the drive speed reference, which is the output of the speed ramp.
