Safe Stop and Safe Stop with Door Monitoring Modes

Safe Stop Wiring Example

This example illustrates safe stop wiring.

Figure 17 - Master, Safe Stop (First or Single Unit)

(1) SCOM must be at the same potential as the drive common because of the encoder signal.

Safe Stop with Door
Monitoring Mode

When properly configured for Safe Stop with Door Monitoring, the drive
monitors the Safe Stop input (SS_In) and initiates the configured Stop Category
upon deactivation of the input as described in

Safe Stop Mode

on

page 55

.

In addition, the drive verifies through monitoring the Door Monitor input
(DM_In) that the door interlock solenoid controlled by the Door Control
output (DC_Out) is in an expected state. The DM_In input is ON when the
door is closed and OFF when the door is open. If the door is monitored as
opened during Safe Stop monitoring, a Door Monitoring fault occurs and the
drive initiates the configured Stop Category.

You can monitor the door’s status with or without using the Door Control (lock/
unlock) function. When door control logic is set to Lock, the drive puts the
solenoid into the locked state when the machine is not at a safe speed or at
Standstill Speed.

Lock Monitoring

If an Operaton mode that includes Door Monitoring is selected and Lock
Monitoring is enabled, the Lock Monitor input (LM_In) signal must be OFF
any time that the Door Monitor input (DM_In) transitions from ON to OFF.

IMPORTANT

If your application uses Lock Monitoring without Door Monitoring, you must
use some means to make sure that the Lock Monitor is not stuck at Lock
indication.
