2.7 H: Terminal Functions
YASKAWA ELECTRIC TOEP C710687 03B FSDrive-MV1000 Parameter Guide 189
Setting 1B: During Baseblock (N.C.)
Output opens to indicate that the drive is in a baseblock state. While Baseblock is executed, output transistors do not
switch and no main circuit voltage is output.
Setting 1C: Motor 2 Selection
Indicates which motor is selected when another output terminal is set up to switch drive operation between two motors
(H1- = 16). Refer to Setting 16: Motor 2 Selection on page 176 for details on switching motors.
Setting 1D: During Regeneration
Terminal closes when the motor is driven in the regenerative mode.
Setting 1E: Restart Enabled
An output set for “Restart enabled” closes when the drive begins attempting to restart after a fault has occurred.
The fault restart function allows the drive to automatically clear a fault. The terminal set to 1E will close after the fault is
cleared and the drive has begun attempting to restart. If the drive cannot successfully restart within the number of
attempts permitted by L5-01, then a fault will be triggered and the terminal set to 1E will open. Refer to L5: Fault
Restart on page 211 for details on automatic restart.
Setting 1F: Motor Overload Alarm (oL1)
An output programmed for this function will close when the motor overload level estimated by the oL1 fault detection
exceeds 90% of the oL1 detection level. Refer to L1-01: Motor Overload Protection Selection on page 201.
Setting 20: IGBT Overheat Pre-Alarm (oH)
Output closes whenever the drive thermistor temperature reaches the level specified by parameter L8-02. Refer to L8-02:
Overheat Alarm Level on page 218 for details on IGBT overheat detection.
Setting 21: User-Set Alarm
The contact output closes when an alarm selected to H2-18 occurred.
Note: This setting is available from the drive software versions S0108 and later.
Setting 22: Mechanical Weakening Detection (N.O.)
Output closes when a mechanical weakening situation is detected. Refer to Mechanical Weakening Detection on
page 214 for details.
Setting 2F: Maintenance Period
Output closes when the cooling fan, DC bus capacitors, or DC bus pre-charge relay may require maintenance as
determined by the estimated performance life span of those components. Components performance life is displayed as a
percentage on the digital operator screen. For details, refer to the FSDrive-MV1000 Instructions (Manual No. TOEP
C710687 02).
Setting 30: During Torque Limit
Output closes when the motor is operating at the torque limit specified by the L7- parameters or an analog input.
This setting can only be used in OLV and CLV control modes. Refer to L7-01 to L7-04: Torque Limits on page 216 for
details.
Status Description
Open Baseblock is being executed.
Closed Drive is not in a baseblock state.
Status Description
Open Motor 1 is selected.
Closed Motor 2 is selected.
