C211 Max. Time of Continuous Supply for Braking Resistance
C211
Range
0 ÷ 32000
0 ; 320.00 sec
Default
200
2.00 sec
Level
ENGINEERING
Address
1211
Function
This parameter determines the max. continuous operating time required for the braking
resistance. If the braking resistance is used for a time
C211
without being activated, the
braking resistance command is automatically disabled for a time of inactivity set in
C212
.
C212 Duty Cycle Braking (Ton/(Toff+Ton))
C212
Range
0 ÷ 100
0 ÷ 100%
Default
10
10%
Level
ENGINEERING
Address
1212
Function
C212
= (Ton/(Ton+Toff))*100
This parameter determines the operating duty cycle allowed for the braking resistance. It is
expressed as a percentage and defines the time of inactivity of the braking resistance when
it is continuously operating for the max. time set in
C211
.
C213 Frequency Increase for Overvoltage Compensation – Smart Voltage Control SVC (Smart Voltage Control)
C213
Range
0 ÷ 1000
0 ÷ 1000 %
Default
0

Address

Control
IFD
Function
If this parameter is set > 0, a value given by
C213
* derivative_voltage_DC (expressed in
V/s) is summed up to the frequency currently set for the motor.
In that way, when DC voltage abruptly changes due to sudden variations of the load
torque, the output frequency is promptly adjusted to compensate for voltage increase and
avoid overvoltage conditions.
A value equal to 0.0200 ensures optimum operation in most applications; however, the
optimum value for this parameter is to be found by trial and error.
Example: Suppose that the DC-bus voltage increases by 3 V in 1 ms, such as 3000 V/s. If
C213
is worth 0.02, the following will be instantly summed up to the present output
frequency:
3000 * 0.02 / 60 * 2 = 2 Hz
for a motor with 2 pole pairs.
This amount, however, is limited to 5% of the present output frequency. As per the
example above, if fout = 30 Hz, the amount value would be limited to 30 * 0.05 = 1.5 Hz.
NOTE
Parameter
C213
has no effect if
C210
= [With Resistance].
