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:
Description

Switch
Selects the delay mode. Must be 1.

t
Fkt
Selects the time range (in seconds)
for the delayed contacts.
User-defined
t
max
Value range: 1 … 300 s.
Adjusts the time within the selected
range in 10% steps.
User-defined
t
Value range: 0.1…1.
Multiply the values of t
max
and t to get the time delay (t
v
= t
max
· t). For example, if the required
time is 30 s, you can set the switches as follows:
• t
max
= 30 s, t = 1 (30 s · 1 = 30 s), or
• t
max
= 300 s, t = 0.1 (300 s · 0.1 = 30 s).
