B2 Dc Braking - YASKAWA E7U Programming Manual

b1-11 Drive Delay Time Setting
Setting Range: 0 to 600 Seconds
Factory Default: 0 Seconds
If a time is set into parameter b1-11, the Drive will delay executing any run command until the b1-11 time has expired.
During Drive delay time execution, the digital operator will display:
Both the ALARM and Run indicators will blink while the Drive waits to execute the Run command.
b1-12 Hand Frequency Reference Selection
Setting
0 Operator (factory default)
1 Terminals
When the Drive is put into the HAND mode, by pressing the HAND key while in Operation, the Speed Command will be set via
the digital operator by default. If it is desirable to have the Speed Command input from the terminals instead of the digital
operator, set b1-12= "1: Terminals".
When the Speed Command is set via the terminals, parameter H3-13 will determine whether analog input
IMPORTANT
terminal A1 or A2 is the Speed Command.

b2 DC Braking

The DC Braking Group contains parameters associated with the DC injection braking feature. Parameters involving the starting
frequency, current level, braking time, and motor pre heat current level are located here
b2-01 DC Injection Braking Start Frequency
Setting Range: 0.0 to 10.0 Hz
Factory Default: 0.5 Hz
Parameter b2-01 sets the output frequency where the Drive begins DC Injection during Ramp to stop. in order to lock the rotor of
the motor and established the end point of the ramp. If b2-01 < E1-09 (Minimum Frequency), then DC Injection begins at E1-09.
Parameter b2-01 also determines the output frequency that the Drive must be at or below before a Zero Speed condition is
considered true. This affects any digital output configured as a Zero Speed signal (H2-0x= "1: Zero Speed").
