Options:
Remote Keypad
Simple 4 wire connection to the SCF drive, the remote keypad provides for drive operation (start, stop, direction and speed) and programming. Includes 3 digit LED. Measures only 3.4in (H) x2.2 in (W). Includes gasketing to meet up to NEMA 4X rated environments.
Dynamic Braking
Packaged Dynamic brake option includes control and resistors in an easy to implement solution for fast stopping or deceleration requirements.
EMC Filter
To meet the EU requirements for susceptibility and emissions of electrical and radiated noise (EN 61800-3 and EN 5501). The footprint design allows the filter to mount between the panel and the drive providing the most efficient use of panel space.
High Frequency Output
1,000 Hz Maximum output frequency for high speed motors
PI Setpoint Control Software
For setpoint control of a process using an analog feedback signal (4-20 mA or 0-10 VDC)
Thru-Hole Mounting
This option allows the inverter heatsink to be mounted through the back of the electrical enclosure or cubicle to reduce overall enclosure size. The heatsink is anodized and gasketed for use in NEMA 4X environments.
