This is set according to the actual revolution of the motor. The displayed value
is the same as this set value. It can be used as a monitoring parameter, which is
convenient to the user. This set value corresponds to the revolution at 50Hz.
CD133 Rated Motor Revolution
Set Range: 0~9999r/min Unit: 1r/min Factory Setting: 1440
The setting of motor no-load current will affect the value of slip compensation.
The current is 100% of the rated current of the motor.
CD134 Motor No-load Current
Set Range:0~100% Unit:1% Factory Setting:40
When the inverter drives the motor the slip becomes bigger due to the increase
of load. This parameter can be set for slip compensation to decrease the slip
and make the running speed of the motor closer to the synchronous revolution
0~1000 is corresponding to 0~10% .
CD135 Motor Slip Compensation
Set Range: 0—1000 Unit: 1 Factory Setting: 0
This parameter is set for the DC braking voltage to the motor at start and stop.
It can be adjusted for different braking voltage. When adjusting the parameter
it must be increased slowly from lower value to high value until the sufficient
braking torque is achieved.
The voltage at maximum frequency is 100% voltage.
CD140 DC Braking Voltage Level
Set Range: 0.0—20.0% Unit: 0.1% Factory Setting: 2.0
CD136—CD139 Reserved
This parameter is set for DC Braking at
start and the lasting time of DC Braking
current to the motor. If it is set to zero it
means DC braking is invalid.
DC braking at start is normally used
in the application, in which the load is
movable when the machine is at stop, such
as windmill. Because of the load existing before the inverter drives, the motor
is often in coasting with an uncertain rotation direction. So the DC braking can
be executed before starting the motor to prevent the inverter from tripping.
This setting is valid only when CD031 is set to 0. For the related parameters
refer to CD031, CD140 and CD041.
CD141 DC Braking Time at Start
Set Range: 0.0—25.0S Unit: 0.1S Factory Setting: 0.0
