Emergency stop safety relay

￭
The time delay on the emergency stop safety relay [A61] is adjustable. Set the delay
according to the application requirements. Make sure that the delay is slightly longer than
the emergency stop deceleration time defined by drive parameter 23.23 Emergency stop
time.
Use the rotary switches on the relay to set the time delay. Refer to the table that follows:
Switch

t
Multiply the values of t
time is 30 s, you can set the switches as follows:
• t = 30 s, t = 1 (30 s · 1 = 30 s), or
max
• t = 300 s, t = 0.1 (300 s · 0.1 = 30 s).
