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
Status
Open Motor 1 is selected.
Closed Motor 2 is selected.
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 once 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
Restart on page 205 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
Setting 20: IGBT overheat pre-alarm (oH)
Output closes whenever the drive thermistor temperature reaches the level specified by parameter L8-02. Refer to
Overheat Alarm Level on page 212
Setting 22: Mechanical weakening detection (N.O.)
Output closes when a mechanical weakening situation is detected. Refer to
page 209 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 Instruction Manual (Manual No.
EZZ010926).
Setting 30: During torque limit
Output closes when the motor is operating at the torque limit specified by the L7-
This setting can only be used in OLV and CLV control modes. Refer to
details.
Setting 31: During speed limit
Output closes when the speed limit has been reached. This function can be used in CLV and control mode.
Status
Open The conditions described below are not present.
1. The frequency reference has reached the upper limit set in d2-01.
2. The frequency reference has fallen to the lower limit set in d2-02 or d2-03.
Closed
3. Parameter b1-05 is set to 1, 2, or 3, and the frequency reference has fallen below the minimum output frequency (E1-
09).
Setting 32: During speed limit in Torque Control
The motor torque and load torque are not in balance, causing the motor to accelerate. An output terminal set to 32 closes
when the motor reaches the speed limit. Refer to
Limit on page 146 for details.
