External Base Block Command (Set Value: 12, 13)
When an SPST-NO (set value: 12) or SPST-NC (set value: 13) input is received, Inverter
outputs are shut OFF. Use these inputs in the following cases to stop Inverter outputs.
·
For switching the motor to free running status when applying an external brake.
·
For stopping Inverter outputs before disconnecting motor wiring when changing the
motor from an Inverter to a commercial power supply.
Note
The external base block only shuts Off the Inverter’s output frequency, and the Inverter’s
internal frequency continues to be calculated as usual. Therefore, if the external base
block is cleared when the frequency is not zero, the frequency calculated at that point will
be output. Because of this, if the baseblock is cleared during deceleration while the motor
is free running, a large discrepancy between the motor speed at that moment and the
Inverter output frequency may result in a main circuit overvoltage (OV) or overcurrent
(OC).
