STO Status Indications
Although they are not and must not be considered part of the safety function, indications of the STO
status are available from the Xenus Plus Compact drive for convenience purposes.
Specifically the J8 LED, two user-accessible data objects bits, and the CME2 Control Panel provide
some information on STO status. The LEDs, data objects, and CME2 are not part of the drive safety
function.
7.3.1 J8 AMP LED
A bi-color LED gives the state of the drive. Colors do not alternate, and can be solid ON or blinking. When
multiple conditions occur, only the top-most condition will be displayed.
When that condition is cleared the next one below will shown.
Red/Blinking
=
Latching fault. Operation will not resume
until drive is Reset
Red/Solid
=
Transient fault condition. Drive will resume
operation when the condition causing
the fault is removed.
Green/Double-Blinking =
STO circuit active, drive outputs are
Safe-Torque-Off
Green/Slow-Blinking
=
Drive OK but NOT-enabled. Will run when enabled.
Green/Fast-Blinking
=
Positive or Negative limit switch active.
Drive will only move in direction not inhibited
by limit switch.
Green/Solid
=
Drive OK and enabled. Will run in response to
reference inputs or communication commands.
7.3.2 STO Circuit Status Data Objects
The
Xenus Plus Compact
has a variety of data objects that can be read by the end user via CANopen,
EtherCAT, or serial communications. The status of the STO circuit is available in ASCII parameter 0x139 and
DS-402 parameter 0x219D. Bits 0 & 1 show the status of the STO-IN1 and STO-IN2 inputs.
Bit 8 has no function in the
Xenus Plus Compact
.
Bit
Safety Circuit Status
0
True (1) when STO-IN1 is de-energized and STO is active
1
True (1) when STO-IN2 is de-energized and STO is active
