Functions of the inputs and outputs
模拟用户分配的输入
After converting to a digital value, the quantity of the analog
inputs can be flexibly adapted via parameters for scaling, filter,
sign selection and offset input. The values are available as con-
nector. This is the reason that the analog inputs can be effective
作为主要设定值,也是补充的数量
setpoint or a limit.
模拟输出
可选的模拟输出可用于输出模拟
signals. Analog signals can be output as bipolar signal or as
绝对值。在这种情况下,缩放,偏移,极性和
filter time can be parameterized. The required output quantities
通过输入连接器在干预点选择
numbers. For instance, speed actual value, ramp-function
generator output, current setpoint, line supply voltage etc.
可以输出。

main contactor is opened. After this, after an adjustable time
after the main contactor has dropped out, the field current is
降低到停滞场电流(这可以是参数 -
ized). The standstill field can e.g. be used as anti-condensa-
tion heating for the motor; to do this, approximately 30 % of the
rated field current must be entered as standstill field. The mo-
TOR风扇必须为100%的田间运营
rated field current. Otherwise, the field winding will be over-
loaded.

二进制用户分配输入:
Additional binary input terminals are available for user-assign-
功能功能。在这种情况下,分配了一个分配器编号
every user-assignable terminal, which can be used for control
functions.
二进制输入函数的示例:
•
Voltage disconnect (OFF 2): For OFF 2 (L signal), the control-
lers are instantaneously inhibited, the current in the armature
circuit is reduced and at
I
= 0,主接触器打开。
这drive coasts down uncontrolled.
•
Quick stop (OFF 3): For a quick stop (L signal), the speed set-

二进制输出
用户分配的信号传导功能可在二进制中获得
输出终端(开放发射极输出)。任何双层器数量,
which can be selected via the associated user-assignable
parameter, can be output for each terminal. The polarity of the
output signal and an adjustable delay time (0 to 10 s) can be
selected using parameters.
Examples of binary output functions:
•
故障:存在故障消息时输出L信号。

This signal is used, for instance, as a zero speed signal.

Switch-on command for a mechanical brake: A motor brake
can be controlled using this signal.
什么时候switching on the drive using the "switch-on" function and
entering "operating enable", an H signal is output to open the
brake, in this case, the internal controller enable is delayed by a
可参数的时间(等待机械制动打开
time to expire). When shutting down the drive using the "shut-
down" function or "quick stop", an L signal is output to close the
brake when speed

internal controller enable is present for a parameterizable time
(等待机械制动的关闭时间到期):
I

被打开。
可以使用“关闭”选择其他操作模式
