Fig. 3 Timing diagram of OSTO_100 option
The Figure 3 above gives an example of how the Emotron OSTO_100 option
reacts to changes in inputs signals
STO1 and STO2 . At starting point we assume
that the motor is running at constant speed and both STO1 and STO2 input
signals are high, STO_STATUS_ISO is low (indicating disabled STO). At time
t
1
, STO1 signal goes low and after additional time of t
response
milliseconds
(@time t
2
), the gate driver is made powerless (regardless of state of input STO2 )
and STO_STATUS_ISO output goes high to indicate an active Safe Torque Off
state. The Emotron OSTO_100 option has a t
response
time of ≤15 milliseconds.
