超速会导致过电压，从而损坏或爆炸蓄电池中的电容器
驱动器的中间电路。
安全说明19
操作中的一般安全
这些说明适用于所有操作驱动器的人员。
警告！遵守这些指示。如果你忽视他们，伤害或死亡，或
可能会损坏设备。
•不得在驱动电源处使用隔离开关控制电机。使用
控制面板启动和停止键或来自外部的启动/停止命令
通过I/O或现场总线接口连接的控制设备。
•在重置故障之前，向驱动器发出停止命令。如果你有一个外部
启动命令的源，如果启动已打开，驱动器将立即启动
故障复位后，除非将驱动器配置为脉冲启动。看到了吗
固件手册。
•在激活驱动控制程序的自动故障复位功能之前，
确保不会发生危险情况。这些功能重置
故障后自动驾驶并继续运行。
注意：当控制位置未设置为本地时，控制面板上的停止键
不会停止驾驶，也不会影响人员安全。
正确接地还可以减少电磁辐射和干扰。
•在多驱动器安装中，将每个驱动器分别连接到保护装置
电源的接地（PE）总线。
•确保保护接地（PE）导体的导电率为：
足够的请参阅第46页的“选择电源电缆”。遵守当地规范
规章制度。
•将电力电缆屏蔽连接到电缆的保护接地（PE）端子
驾驶
•在电缆入口处对电源和控制电缆屏蔽进行360°接地
以抑制电磁干扰。
注:
•只有在电缆屏蔽层正常工作时，才能将电缆屏蔽层用作接地导体
导电性足够。
•标准IEC/EN 61800-5-1（第4.3.5.5.2节）要求：
如果驱动器的电流高于3.5 mA AC或10 mA DC，则必须使用固定电源
保护接地（PE）连接。此外
•安装具有相同横截面积的第二根保护接地导线
作为原始保护接地导体，
或
•安装横截面至少为10 mm2 Cu的保护接地导线
或16mm2 Al，
或
•安装一个装置，如果保护装置损坏，该装置将自动断开电源
接地导体断裂

Additional instructions for permanent magnet motor drives
 Safety in installation, start-up and maintenance
These are additional warnings concerning permanent magnet motor drives. The other
safety instructions in this chapter are also valid.
WARNING! Obey these instructions. If you ignore them, injury or death and
damage to the equipment can occur.
• Do not work on a drive when a rotating permanent magnet motor is connected
to it. A rotating permanent magnet motor energizes the drive including its input
power terminals.
Before installation, start-up and maintenance work on the drive:
• Stop the motor.
• Disconnect the motor from the drive with a safety switch or by other means.
• If you cannot disconnect the motor, make sure that the motor cannot rotate during
work. Make sure that no other system, like hydraulic crawling drives, can rotate
the motor directly or through any mechanical connection like felt, nip, rope, etc.
• Measure that the installation is de-energized.
• Use a multimeter with an impedance of at least 1 Mohm.
• Make sure that the voltage between the drive output terminals (T1/U, T2/V,
T3/W) and the grounding (PE) busbar is close to 0 V.
• Make sure that the voltage between the drive input power terminals (L1, L2,
L3) and the grounding (PE) busbar is close to 0 V.
• Make sure that the voltage between the drive DC terminals (UDC+, UDC-) and
the grounding (PE) terminal is close to 0 V.
• Install temporary grounding to the drive output terminals (T1/U, T2/V, T3/W).
Connect the output terminals together as well as to the PE.
Start-up and operation:
• Make sure that the operator cannot run the motor over the rated speed. Motor
overspeed causes overvoltage that can damage or explode the capacitors in the
intermediate circuit of the drive.
Safety instructions 19
General safety in operation
These instructions are for all personnel that operate the drive.
WARNING! Obey these instructions. If you ignore them, injury or death, or
damage to the equipment can occur.
• Do not control the motor with the disconnector at the drive power supply. Use the
control panel start and stop keys or the start/stop commands from an external
control device connected through the I/O or fieldbus interface.
• Give a stop command to the drive before you reset a fault. If you have an external
source for the start command and the start is on, the drive will start immediately
after the fault reset, unless you configure the drive for pulse start. See the
firmware manual.
• Before you activate automatic fault reset functions of the drive control program,
make sure that no dangerous situations can occur. These functions reset the
drive automatically and continue operation after a fault.
Note: When the control location is not set to Local, the stop key on the control panel
will not stop the drivethe personnel safety.
Proper grounding also reduces electromagnetic emission and interference.
• In a multiple-drive installation, connect each drive separately to the protective
earth (PE) bus of the power supply.
• Make sure that the conductivity of the protective earth (PE) conductors is
sufficient. Refer to Selecting the power cables on page 46. Obey the local
regulations.
• Connect the power cable shields to the protective earth (PE) terminals of the
drive.
• Make a 360° grounding of the power and control cable shields at the cable entries
to suppress electromagnetic disturbances.
Note:
• You can use power cable shields as grounding conductors only when their
conductivity is sufficient.
• Standard IEC/EN 61800-5-1 (section 4.3.5.5.2.) requires that as the normal touch
current of the drive is higher than 3.5 mA AC or 10 mA DC, you must use a fixed
protective earth (PE) connection. In addition,
• install a second protective earth conductor of the same cross-sectional area
as the original protective earthing conductor,
or
• install a protective earth conductor with a cross-section of at least 10 mm2 Cu
or 16 mm2 Al,
or
• install a device which automatically disconnects the supply if the protective
earth conductor breaks
