产品详情资料
图5.9/3用于使装置PW1002/3适应风扇电流。X轴
标准化为1并表示风扇电流。负载电阻为60
欧姆(等于默认值):1等于5A。Y轴在输出中按比例缩放
电压(外部上拉电阻为2k2至5V)作为转换器电子设备的输出信号。2 V和3 V范围内的值值得关注,因为可以通过软件使用温度设置参数将这些值设置为阈值。如果电流低于/高于交叉点-参数值/选定曲线,转换器将生成错误消息。

CZD-01板还具有所有晶闸管的阴极/阳极电压测量。电压测量提供了以下方面的清晰检测:
直流负载条件。
零电流检测的要求是:
•实际负载电流低于低阈值
•上部三轴器堵塞(V11、V13、V15…)
或下部晶闸管被阻断(V12、V14、V15…)
必须通过参数在软件中设置板的激活:
DCF500 4.19零电流检测
DCF600 43.14零电流检测Fig. 5.9/3 is used to adapt the device PW1002/3 to the fan current. The X-axis
is normalized to 1 and represents the fan current. With a burden resistor of 60
Ohms (equal to default) the 1 is equal to 5 A. The Y-axis is scaled in output
voltage (with external pull-up resistor of 2k2 to 5 V) as the output signal towards the converter electronics. Values within 2 V and 3 V are of interest, because these values can be set via software as a threshold, using the temperature setting parameter. The converter generates an error message, if the current is lower / higher than the intersection -parameter value / -selected curve.

5.10 Zero current detection SDCS-CZD-01
This board is used for fast zero current detection
especially for three phase field converter in Motor
Generator application. The board provides a safe
zero current detection also for other very big load
inductances.
The board is located on SDCS-CON-2 board and
plugged on X12, X13 and X17.
X17: is only used for mechanical reasons. The
electrical function (connection to IOE-1) is unchanged.
All DCS/DCF converter are equipped with a zero
current detection by monitoring the current signal to
a certain level. X13:
Fig. 5.10/2 Connection between the SDCS-CZD-01 and SDCS-CON-2 board
The CZD-01 board has in addition a cathode / anode voltage measurement of all thyristors. The voltage measurement provides a sharp detection of
DC load condition.
The requirement for zero current detection is:
• actual load current falls below a low treshold
• AND upper thristors are blocked (V11,V13,V15..)
OR lower thyristors are blocked (V12,V14,V15..)
The activation of the board must be set in the software via parameter:
