Setting 6: Drive ready (READY)
Output closes whenever the drive is ready to operate the motor. The terminal will not close under the conditions listed
below, and any Up/Down commands will be disregarded.
• When the power is shut off
• During a fault
• When the internal power supply of the drive has malfunctioned
• When a parameter setting error makes it impossible to run
• Although stopped, an overvoltage or undervoltage situation occurs
• While editing a parameter in the Programming Mode (when b1-08 = 0)
• When parameter L8-88 = 0 and at least one Safe Disable input is open
Setting 7: DC bus undervoltage
Output closes whenever the DC bus voltage or control circuit power supply drops below the trip level set in L2-05. A
fault in the DC bus circuit will also cause the terminal to set for “DC bus undervoltage” to close.
Setting 8: During baseblock (N.O.)
Output closes to indicate that the drive is in a baseblock state. While in baseblock, output transistors do not switch and no
main circuit voltage is output.
Setting 9: Speed reference source
Displays the currently selected speed reference source.
Setting A: Up/Down command source
Displays the currently selected Up/Down command source.
Status
Description
Open
DC bus voltage is above the level set to L2-05
Closed
DC bus voltage has fallen below the trip level set to L2-05.
Status
Description
Open
