1) The total load capacity of +24V-DCM internal 24V power is 60 mA, and only supplies power for the MI
terminal of NPN and PNP mode. If you want to know available load capacity to support other external
accessories, deduct the load consumed by corresponding MI terminals. Each MI terminal consumes 6mA.
2) The power supply of the cooling fan is 24V
DC
. Internal power is applied from terminal +24V/DCM. Once you
install a cooling fan on VFD007EL21W(-1), do not connect any other external accessory to avoid overload
on terminal +24V which will damage the motor drive.
