Frequently Asked Questions
Does VFD7A5MS21ANSAA include a built-in EMC filter?
No. The N in this model code means no built-in EMC filter. Delta also builds a filtered version of the same rating, with an F in place of the N. Tell us which one you need and we will quote the correct part number.
What motor size does VFD7A5MS21ANSAA drive?
It is rated for a 1.5 kW (2 HP) three-phase induction motor, with a rated output current of 7.5 A.
Can VFD7A5MS21ANSAA replace an older Delta VFD-M, VFD-L, VFD-S or VFD-B drive?
Yes. Delta recommends the MS300 as the replacement for the discontinued VFD-M, VFD-L and VFD-S series and for the smaller VFD-B ratings. Match the motor current rather than the old model number when you select the replacement.
Which fieldbus options are available for VFD7A5MS21ANSAA?
RS-485 Modbus RTU is built in. The option card slot accepts CANopen, PROFIBUS DP, DeviceNet, EtherNet/IP, PROFINET and EtherCAT cards.
