(10) DC feeding mode1 [Pr. 30 = 10, 11]
Setting [
Pr. 30
= 10, 11] enables DC power supply
operation. Built-in brake transistor control is valid.
Leave the AC power supply connection terminals R/
L1, S/L2, and T/L3 open and connect the DC power
supply to terminals P/
+
and N/-. Also, remove
jumpers across terminals R/L1 and R/1/L11 and
across terminals S/L2 and S1/L21. And connect
terminals R1/L11 and S1/L21 to terminal P/
+
and N/-.
The diagram below is a connection example.
(11) DC feeding mode 2 [Pr. 30 = 20, 21]
When [
Pr. 30
= 20, 21], operation is performed with
AC power normally and with DC power such as
battery at power failure. Built-in brake transistor
control is valid.
Connect the AC power supply to terminal R/L1, S/L2,
and T/L3 and connect the DC power supply to
terminal P/
+
and N/-. Also, remove jumpers across
terminal R/L1 and R/1/L11 and across terminal S/L2
and S1/L21. And connect terminals R1/L11 and S1/
L21 to terminal P/
+
and N/-.
Turning ON the DC feeding operation permission
signal (X70) enables DC power supply operation.
The following shows the connection diagram when
switching to a DC power using inverter power failure
detection.
