If there is a blinking digit, press
/ / to modify the digit.
• After you set the user password (set FP-00 to a non-zero value), the system requires
user password authentication (the system displays "------") when you press PRG. In this
case, you can modify the function code parameters only after entering the password
correctly.
• For factory parameters (group FF), you also need to enter the factory password.
• Do not try to modify the factory parameters. If these parameters are set improperly, the
system may be unstable or abnormal.
• In the password protection unlocked state, you can change the password at any time.
The last input number will be the user password.
• If you want to disable the password protection function, enter the correct password
and then set FP-00 to 0. If FP-00 is a non-zero value at power-on, the parameters are
protected by the password.
• Remember the password you set. Otherwise, the system cannot be unlocked.
5.2 System Application
5.2.1 Emergency Evacuation at Power Failure
Passengers may be trapped in the car if power failure suddenly happens during the use of
the elevator. The emergency evacuation function at power failure is designed to solve the
problem.
The emergency evacuation function is implemented in the following two modes:
• Uninterrupted power supply (UPS)
• Shorting PMSM stator
The two modes are described in detailed in the following part.
■
Emergency Evacuation 220 V UPS
In this scheme, the 220 V UPS provides power supply to the main unit and the drive control
circuit. The following figure shows the emergency evacuation 220 V UPS circuit.
