The safety input function meets EN ISO 13849-1 PLd and EN 61508 SIL2
(EN60204-1, stop category 0)
Safe input function circuit
CAUTION
The STO safety function does not disconnect the main input power
and auxiliary power supply. The drive disconnects the output motor
power supply. Therefore, active conductors may be present inside so
do not carry out electrical maintenance tasks without isolating the
drive. Otherwise, it could cause damage to the equipment and lead to injury
and even death.
Do not use the STO function as a normal drive stop.
According to EN 60204-1 automatic restart is not allowed after an
emergency stop. For this reason, the machine control must prevent
an automatic start after emergency stop.
