Commonly used status commands (binary status bits are
numbered 1 to n, from left to right):
TERRLG Error log reports the last 10 error conditions
(cleared with CERRLG).
TAS
General report, including fault conditions.
TASX
Additional report of conditions not covered with
TAS.
TCS
If TASX bit #7 or bit #28 is set, you can identify
the cause with TCS.
TINO
Bit #6 indicates status of Enable input ("1" = OK
to enable drive).
TIN
Status of digital inputs, including end-of-travel
inputs.
TOUT
Status of digital outputs.
You must configure all motor parameters. Be sure to follow
the drive configuration procedure (see
Chapter 2 Installation
).
Any fault condition causes the drive to shut down.
The drive can not be enabled (DRIVE1) unless the Enable
input is grounded and the Reset input is not grounded.
Use one of three methods to reset the drive (all command
settings are remembered after reset):
Issue the RESET command.
Momentarily close the Reset input.
Cycle power to the drive.
