Pollution Degree PD 2
Supported Motors 1 x 3-phase BLDC-Motor and 1 active
brake
Attention
Servo drives including STO-SBC module shall be used only in Pollution Degree environments class PD 2
according to IEC 61800-5-1: During normal operation only non-conductive pollution may occur,
temporarily occurring conductivity caused by condensation may only be expected when the servo drive
is out of operation.
