F2.02 Stop mode
Setting range: 0 ~ 1
0: Deceleration stop
The inverter stops after its output frequency decreases gradually according to the
set acceleration time.
1: Free stop
When stopping, the inverter outputs zero frequency and locks output signals, and
the motor rotates freely and then stops. At the free stop, it is required to restart the
motor after the motor has completed stopped running. Otherwise, over current or
overvoltage fault may occur.
F2.03 DC braking initial frequency at stop
F2.04 DC current at stop
F2.05 DC braking time at stop
Setting range: 0.0 ~ [F0.04]
Setting range: 0.0 ~ 100%
Setting range: 0 ~20.0 Sec.
This parameter group is used to set DC braking parameters at stop.
During the process of DC braking initial frequency ([F2.03]) at stop setting inverter
stop, when the output frequency is lower than the set parameter, the inverter will
lock output and enable DC braking function. The stop DC braking action time is to
be set by parameter [F2.05]. The stop DC braking action time is set to 0, the stop
DC braking function is ineffective.
Stop DC braking current means the percentage of inverter’s rated current.
F2.06 Acceleration torque level
Setting range: 110 ~ 200（％）
This parameter is used to set the allowed output level of torque current at accelerateon.
The torque limiting level during inverter acceleration is set by [F2.06]. It is set to
the percentage of inverter’s rated current. For example, if it is set to 150%, it means
the output current is 150% of the rated current at maximum.
When the inverter’s output current is higher than the level specified by these
parameters, the acceleration and deceleration time will be prolonged automatically
so as to confine the output current within this level range. Refer to Figure 6-13.
