<Response time>
Safety input 1 or 2 enables STO to operate: within 5 ms of response time, the motor
output torque will be turned off.
Caution
Safety output signal from the safety controller and safety sensor may include L pulse for
self-diagnosis.
To prevent the L pulse from mis-triggering STO function, the safety input circuit has
