Chapter 5 Parameter Introductions
P1.13 Dynamic braking selection
0: Dynamic braking is disabled
2: Magnetic flux braking is enabled
 Tips:
dynamic braking and magnetic flux braking are enabled automatically
If setting is 3,
in deceleration to improve the control capability; in occasion of high moment of
inertia and demand of fast shut down, the parameter can be set to 1 and choose the
matched braking resistor; if
output current can be large.
Only valid to inverter that power is lower than 3015GB/3018PB
P1.14 Voltage of working time of braking
(3004GB/35R5PB and below)
P1.14 Utilization ratio of working time of
braking (35R5GB/37R5PB and above)
Note:
 3004GB/35R5PB and below: P1.14 is set as braking point voltage, it cannot be set
too low and need consider the inverter model..
 35R5GB/37R5PB and above
taken into consideration when setting this parameter. If set to 5.0%, total DC
injection braking time in effect will be equal to 5.0s; Start point of DC injection
braking voltage: 710V
P1.15 Trip-free treatment
0: once trip-free, report Uu1
2: once trip-free, give Uu alarm
Note:
◆If having the speed track optional parts, P1.15 could set to 1 or 2.
P1.16 Trip-free time
Note:
 If under voltage occurs in trip-time, the inverter will display Uu alarm only, and the
motor cannot startup at this time. As shown in Fig. 5-1-7:
 If under voltage occurs in running, the inverter will display "Uu" alarm and "Uu1"
fault, as shown in Fig.5-1-7. PWM output inhibits, motor runs at zero-speed. If the
92
deceleration can be achieved but the
setting is 2, fast
Range: 360~750【1 phase:380V
Three-phases: 700V】
Range: 0.0~100.0%【100.0%】
Resistance and power of the braking resistor must be
:
Range: 0~2【0】
1: In trip-free time give Uu1 alarm,
otherwise report Uu1
Range: 0.5~10.0s 【 This value depends on the
inverter model】
Range: 0~3【1】
1: Dynamic braking is enabled
3: Both are enabled
