■ Usage example 2: Outputting braking signals
The following shows an example for outputting the excitation/release signals for the electromagnetic
brake.
To output the braking signals from the terminals [R1A]-[R1C], make setting as follows:
• <F133: Terminal R1 function 1> = "4: Low-speed signal" (default setting)
• <F100: Low-speed signal output frequency> = "2.5" (Hz) (setting example)
Set <F100> to the value for the motor rated slip.
