8.4 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 Accelnet & Stepnet Plus Panels drive for convenience purposes.

Specifically the Axis A & B LEDs, 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.

8.4.1 Axis A & B LEDs

The example shown is for a 2-axis drive. On 1-axis drives the AMP LED is located apart from the RS-232

connector. 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.

8.4.2 STO Circuit Status Data Objects

The

Accelnet & Stepnet Plus Panel

s have 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

Accelnet & Stepnet Plus Panel

Bit

Safety Circuit Status

Set (1) when STO-IN1 is active and preventing the drive from producing torque

Set (1) when STO-IN2 is active and preventing the drive from producing torque
