伺服驱动器也可以作为转矩控制驱动器操作。
在主-从驱动或串联驱动中主驱动器决定从驱动器的速度。这样操作模式：扭矩设定点被转移到设定点输入
从速度控制的主驱动器到从驱动器。
应注意，主驱动和从驱动的电机轴必须机械连接在一起，无间隙，以防止施加扭矩时，从动装置在无负载扭矩的情况下加速。这联轴器必须尽可能刚性和抗扭刚度，以防止：机械系统中的振动。
主驱动器和从驱动器之间的连接如所示图。12至16.MOD编程模块应特别配置用于从驱动器。
系统或伺服驱动器中的故障无法在紧急停止情况。因此，在这种情况下，有必要隔离
通过主电源从主电源供电的驱动器电源部分接触器，以便安全停止伺服驱动（通过打开紧急停止电路）。
在伺服驱动停止之前，必须始终假设存在故障，并且可能发生危险的驾驶移动，其程度取决于故障类型和发生时驱动器的运行状态。
必须提供更高级别的安全措施，以确保驱动器：一般情况下，通过紧急停止电路断开
故障如果单独操作时必须降低驱动器的峰值扭矩
机器条件下，最大扭矩可从外部限制
由用户通过Ired模拟输入。在这种情况下，模拟电压
应用于Ired输入。电压URE的值取决于期望减小系数k=最大扭矩的减小扭矩：
URE=10伏•（1-k）减少的电机电流Ired的值可从图。9和10.扭矩可根据电流计算
使用中电机的扭矩常数km，可从第10.1节中的表格：M=km•Ired
最小可调节扭矩被限制为最小值。这个相关的最小可调电机电流可从第10.2节中的表格。
如果Ired输入没有可用的模拟电压，则扭矩减小值：电阻R（ex）可连接在Ired端子和通过继电器触点连接+15 VM端子。
The servo drive can also be operated as a torque-controlled drive.
In the master-slave drive or tandem drive the speed controller of the
master drive determines the speed of the slave drive. In such an
operating mode the torque set-point is transferred to the set-point input
of the slave drive from the speed-controlled master drive.
It should be noted that the motor shafts of the master and slave drives
must be mechanically coupled together without backlash to prevent the
slave drive accelerating without load torque when torque is applied. This
coupling must be as rigid and as torsionally stiff as possible to prevent
oscillations in the mechanical system.
Connections between the master drive and the slave drive are shown in
Figs. 12 to 16. The MOD programming module should be specially
configured for the slave drive.
A malfunction in the system or servo drive cannot be eliminated in an
emergency-stop situation. It is therefore necessary in this case to isolate
the power section of the drive from the mains supply via the mains
contactor in order to stop the servo drive safely (by opening the
emergency-stop circuit).
Until the servo drive is stopped it must always be assumed that faulty and
dangerous drive movement can occur, the extent of which depends on
the type of fault and the operating state of the drive at the time it occurs.
A higher-level safety measure must be provided to ensure that the drive
disconnected via the emergency-stop circuit in the event of a general
malfunction. If the peak torque of the drive has to be reduced for individual operating
conditions on the machine, the maximum torque can be limited externally
by the user via the Ired analogue input. In this case an analogue voltage
is applied to the Ired input. The value of the voltage Ured depends on the
desired reduction factor k = reduced torque to maximum torque:
Ured = 10 volts • (1 - k)
The value of the reduced motor current Ired can be obtained from the
graphs in Figs. 9 and 10. The torque can be calculated from the current
torque constant km of the motor in use, which can be obtained from the
table in Section 10.1:
M = km • Ired
The smallest adjustable torque is limited to a minimum value. The
associated minimum adjustable motor current can be obtained from the
table in Section 10.2.
If no analogue voltage is available for the Ired input, for a reduced torque
value a resistor R(ex) can be connected between the Ired terminal and
the +15 VM terminal via a relay contact.
