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.

Table 2.14 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 parameters to meet these conditions at the same time. If the setting is too high, overshoot is possible at start.

*3 Use L4-02 to adjust the detection width of Frequency Detection 2. If rollback occurs when the motor is stopped, set the frequency to
approximately 0.1 Hz.
