電源電壓施加后，驅(qū)動(dòng)放大器發(fā)出信號(hào)
當(dāng)它們“準(zhǔn)備就緒”時(shí)，伺服驅(qū)動(dòng)器可以通過(guò)以下方式以受控速度運(yùn)行：–在射頻輸入端注入控制器啟用信號(hào)，以及–施加與電機(jī)成比例的模擬設(shè)定點(diǎn)電壓速度，跨輸入
?E1和E2或?E3和0虛擬機(jī)或?E4和0虛擬機(jī)。
可以進(jìn)行以下設(shè)置：（參見(jiàn)圖8中的伺服驅(qū)動(dòng)模塊）。
輸入E1-E2是差分輸入，輸入E3和E4是求和輸入它們被稱(chēng)為0 VM。
速度加權(quán)（輸入靈敏度）已在中設(shè)置MOD編程模塊上的工廠。提供了兩種設(shè)施：電阻器和電位計(jì)值并入MOD根據(jù)所需的輸入權(quán)重對(duì)模塊進(jìn)行編程使用者
編程模塊類(lèi)型名稱(chēng)的最后三位數(shù)字指定：輸入加權(quán)（見(jiàn)第3.2節(jié)）。
如果沒(méi)有可用的用戶(hù)數(shù)據(jù)，則MOD編程模塊將給出
每最大速度值10伏的輸入加權(quán)（無(wú)調(diào)整電位計(jì)）。
NC輸出的速度設(shè)定點(diǎn)可以平滑，如果樓梯功能明顯受到干擾。應(yīng)該注意的是，過(guò)度平滑可以降低位置控制的動(dòng)態(tài)響應(yīng)，并且從而減慢反應(yīng)時(shí)間。
設(shè)定點(diǎn)平滑只能通過(guò)使用微分來(lái)實(shí)現(xiàn)輸入E1-E2。通過(guò)將電容器C5焊接到
MOD編程模塊（最大可達(dá)3uF，對(duì)應(yīng)于大約5至7ms的平滑時(shí)間常數(shù)）。
當(dāng)電機(jī)順時(shí)針旋轉(zhuǎn)時(shí)，從輸出軸看旋轉(zhuǎn)方向如下：差分輸入E1-E2：E1處的電壓為正關(guān)于E2
對(duì)輸入E3、E4求和：E3或E4處的電壓為負(fù)關(guān)于0VM
T處的轉(zhuǎn)速計(jì)測(cè)量信號(hào)（感測(cè)）：電壓相對(duì)于對(duì)于0VM，如果另一個(gè)旋轉(zhuǎn)方向是：
渴望的：–在差分輸入E1-E2處交換連接，如果使用，–通過(guò)連接端子X(jué)6/9和X6/10，反轉(zhuǎn)所有輸入的方向在控制放大器處。通過(guò)互換電機(jī)連接來(lái)反轉(zhuǎn)旋轉(zhuǎn)方向
這是不可能的，并導(dǎo)致驅(qū)動(dòng)器故障。速度控制器具有極低的溫度漂移。零可以在底部的“調(diào)零”電位計(jì)上校正漂移前面板右側(cè)（第5.2.2節(jié)圖35至40中的前視圖）。應(yīng)始終在初始操作和更換后檢查漂移
伺服驅(qū)動(dòng)模塊：如果軸以零速度設(shè)定點(diǎn)移動(dòng)，則軸的旋轉(zhuǎn)運(yùn)動(dòng)應(yīng)通過(guò)上的“調(diào)零”電位計(jì)設(shè)置為零控制柜達(dá)到最終溫度時(shí)的前面板。
After the mains voltage has been applied and the drive amplifiers signal
that they are ?ready“, the servo drive can be run at controlled speed by
– injecting the controller enabling signal at the RF input and
– applying an analogue set-point voltage, that is proportional to the motor
speed, across the inputs
? E1 and E2 or
? E3 and 0 VM or
? E4 and 0 VM.
The following settings are possible: (see basic circuit diagram of the
servo drive module in Fig. 8).
Input E1-E2 is a differential input, inputs E3 and E4 are summing inputs
that are referred to 0 VM.
The speed weighting (input sensitivity) has already been set in the
factory on the MOD programming module. Two facilities are provided The resistor and potentiometer values are incorporated into the MOD
programming module according to the input weighting required by the
user.
The last three digits of the programming module type designation specify
the input weighting (see Section 3.2).
If no user data are available, the MOD programming module is given the
input weighting of 10 volts per max. speed value (no adjustment
potentiometer).The speed set-point output by the NC can be smoothed if the staircase
function becomes noticeably disturbed. It should be noted that excessive
smoothing can reduce the dynamic response of the position control and
thus slow the reaction time.
Set-point smoothing can be implemented only by using the differential
input E1-E2. Smoothing is provided by soldering a capacitor C5 onto the
MOD programming module (up to a maximum of 3uF is possible,
corresponding to a smoothing time-constant of approximately 5 to 7 ms).
With the motor rotating clockwise, as viewed from the output shaft, the
direction of rotation is as follows:
Differential input E1-E2: voltage at E1 is positive
with respect to E2
Summing inputs E3, E4: voltage at E3 or E4 is negative
with respect to 0VM
Tacho measuring signal at T(sense): voltage is positive with respect
to 0VM The following facilities are provided if another direction of rotation is
desired:
– Interchange the connections at differential input E1-E2, if this is used,
– Reverse the direction of all inputs by linking terminals X6/9 and X6/10
at the control amplifier.
Reversing the direction of rotation by interchanging motor connections
is not possible and causes the drive to malfunction.
The speed controller has an extremely low temperature drift. The zero
drift can be corrected on the ?ZERO ADJ“ potentiometer at the bottom
right of the front panel (front view in Figs. 35 to 40 in Section 5.2.2).
The drift should always be checked at initial operation and after replacing
the servo drive module:
If the axis moves with a zero speed set-point, the rotary motion of the axis
should be set to zero by means of the ?ZERO ADJ“ potentiometer on the
front panel when the control cabinet has reached its final temperature.
