■ Notes for Elevator Applications
When using the drive for elevator applications, read the safety descriptions and precautions, and safely and
correctly use the device.
Conditions to Open and Close the Brake
Set L4-07 = 0 [Speed Agree Detection Selection = No Detection during Baseblock] to open and close the holding
brake.
When L4-07 = 1 [Detection Always Enabled], the output frequency increases when you input the Run command
although the external baseblock command is input. Because of this, speed detection operates and will open the
brake signal.
• Set Related Parameters
Table 11.18 shows examples of parameter settings to use the MFDO terminal (M1-M2) as the holding brake
open and close signal.

*1 When A1-02 = 7 [PM Closed Loop Vector], make sure that the motor can rotate before you do Auto-Tuning or switch the encoder.
Refer to Closed Loop Vector Control for induction motors for information about the signal to use and the adjustment method.
*2 When A1-02 = 2 [Open Loop Vector], it is the usual setting range. When A1-02 = 0 [V/f Control], set L4-01 to the rated slip
frequency of the motor + approximately 0.5 Hz. If you set the value too low, motor torque will not be sufficient and it will cause
motor rollback. Set the parameter to agree with these conditions: If you set the value too high, there will be overshoot during start up:
• L4-01 > E1-09 [Minimum Output Frequency]
• L4-01 > L4-02 [Speed Agree Detection Width]
*3 Use L4-02 to adjust the detection width of Frequency Detection 2. If rollback occurs when the motor is stopped, change the
frequency to approximately 0.1 Hz.

Sequence Circuit Configuration
Use these conditions to set the circuit for the open/close sequence of the holding brake:
• Set the sequence-side operation conditions to activate terminal M1-M2 and open the holding brake.
• Set the sequence to close the holding brake in an emergency if the drive detects a fault.
