Frequently Asked Questions
The STO function disables the control voltage of the power semiconductors, preventing the drive from generating torque to rotate the motor. This safety feature ensures the motor cannot start unexpectedly during maintenance.
The ACS355-03E-04A1-4 supports Modbus RTU and CANopen communication protocols, enabling easy integration with PLC systems and industrial networks.
No, the ACS355-03E-04A1-4 is designed specifically for three-phase AC induction motors. For single-phase applications, different drive models should be considered.
The drive and input power cable must be protected with correct fuses. IEC/EN/UL 61800-5-1 requires two PE conductors if the cross-sectional area is less than 10 mm² Cu or 16 mm² Al.
The drive operates in ambient temperatures from -10°C to +50°C (14°F to 122°F) and should be installed in well-ventilated areas to ensure proper cooling.
Trust and Certification
The ABB ACS355 series complies with international standards including:
- IEC/EN/UL 61800-5-1 for drive safety
- IEC 60204-1 for machinery electrical equipment safety
- IEC 61508 for functional safety requirements
