N700E INSTRUCTION MANUAL
3-22
A34
DC Injection Braking Frequency Setpoint
Range: 0.50 ~ 10.00 Hz in 0.01 Hz
Program the VFD frequency out when DC injection braking function kicks in. If set A34 to
0.5Hz, when VFD frequency out reaches to 0.5 Hz, DC braking function is activated.
Related Parameters: A33~A37
A35
DC Injection Braking Delay Time
Range: 0.0 ~ 5.0 Sec in 0.1 Sec
Program the delay time when the DC braking function actually starts form when VFD out
is the frequency value in A34.
Related Parameters: A33~A37
A36
DC Injection Braking Force at Stop
Range: 0.0 ~ 100.0 % in 0.1 % Depending on the N700E Type
Program the level of DC injection braking force of rated electric power of N700E
Related Parameters: A33~A37
A37
DC Injection Braking Time at Stop
Range: 0.0 ~ 10.0 Sec in 0.1 Sec
Program the DC Injection Braking duration
