5.7 H: Terminal Functions
Setting 6: Drive 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 o f 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.
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.
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.
Status
Description
Open
Drive is not in a baseblock state.
Closed
Baseblock is being executed.
Setting 9: Speed reference source
Displays the currently selected speed reference source.
Status
Description
Open
Speed reference is provided from External reference 1 (b1-01).
Closed
Speed reference is being sourced from the digital operator.
Setting A: Up/Down command source
Displays the currently selected Up/Down command source.
Status
Description
Open
U p/Dow n command is provided from External reference 1 (b1-02).
Closed
U p/Dow n command is being sourced from the digital operator.
Setting B, 18: Torque detection 1, Torque detection 2
These digital output functions to signal an overtorque or undertorque situation to an external device.
Set up the torque detection levels and select the output function from the table below. Refer to
L6: Torque Detection on
page 196
for details.
Setting
Status
Description
B
Closed
Torque detection 1 :
Output current/torque exceeds (overtorque detection) or is below (undertorque detection) the torque value set in parameter L6-02 for longer than
the tim e specified in parameter L6-03.
18
Closed
Torque detection 2 :
Output current/torque exceeds (overtorque detection) or is below (undertorque detection) the torque value set in parameter L 6-05 for longer than
the tim e specified in parameter L6-06.
Setting E: Fault
The output closes when the drive faults (excluding CPF00 and CPF01 faults).
