Braking resistance
Control mode
VF FOCPG FOCPM
Factory setting: 0.0
Settings 0.0 ~ 6553.5Ω
Set Pr.02-39 =1 (Enable detection of braking resistor at startup), then as soon as the hybrid servo drive is
powered on, a checkup will be performed to know if the braking resistance is appropriate and if the braking
resistor is working properly.
If the braking resistance is too small, the braking resistor could be on an open circuit or is not properly
installed. The error code <bro> will be displayed on the keypad.
If the braking resistance is smaller than the allowable minimum resistance or is on a short circuit, the error
code < brF > or < ocbS> will be displayed on the keypad.
Pr.02-40 is the detected braking resistance.
Decode the parameter protection with the password
Control mode
Factory setting: 0
Settings 0~9999
Display 0~3 times of entering wrong password
Enter the password set at Pr.02-22 into Pr.02-21, and then the parameters will be unlocked for modifications.
Write down the setting vale after you set up this parameter to avoid inconveniences.
Use Pr.02-21 and Pr.02-22 to prevent any unauthorized personnel to modify/ delete parameters.
If you forget the password, input 9999 and press ENTER, then repeat inputting 9999 and pressing ENTER to
complete the decoding procedure (This procedure has to be done in 10 seconds, if you don’t finish that in 10
seconds, repeat the same procedure until you finish the procedure in 10 sec.). Once you finish this decoding
process, all the parameters will be back to the factory settings.
When setting up a password, all the parameters will be read as 0, except Pr.02-22
Set up a parameter protection password
Control mode
Factory setting: 0
Settings 0~ 9999
Display 0: No password set or password entered successfully in Pr.02-21.
1: Parameters are locked
This parameter is for setting up a password to protect parameters. When you finish setting up a password,
keypad will display 1, which means the password protection is now effective.
Once you input the correct password into Pr.02-21, the hybrid servo drive is temporarily unlocked. To cancel
the parameter protection, set Pr.02-22 =0. Once the parameter protection is cancelled, the hybrid servo
drive is without password protection even after reboot.
Decode temporarily or cancel the password then you will be able to use keypad to copy parameters. But the
password set at Pr.02-22 will not be copied. When the parameters saved in the keypad are transferred to
