4.10 Low voltage operation
With the addition of a 24 Vdc power supply to supply the control circuits, the drive is able to operate from a low voltage DC supply with a range of
voltages from 24 Vdc to the maximum DC voltage for the given drive. The working voltage ranges for the low voltage DC power supply are as follows:
Size 3 to 7
Minimum continuous operating voltage: 26 V
Minimum start up voltage: 32 V
Maximum over voltage trip threshold: 200 V drives = 415 V, 400 V drives = 830 V, 575 V drives = 990 V, 690 V drives = 1190 V
