Quick Guide
1 - Technology
W21 Magnet Drive System is a system composed of the W21 Magnet permanent magnet synchronous
motor and the WEGPM frequency inverter.
The W21 Magnet motor features three-phase stator winding, similar to an induction motor, and rotor
assembled with permanent magnets instead of a squirrel cage. The permanent magnets eliminate the need
of current induction on the rotor (magnetizing current); therefore, with no load the motor presents a very low
current, just enough to make up for the losses. Besides the magnetizing current, the W21 Magnet does not
require slip compensation either, since the shaft speed does not vary with the load.
All W21 Magnet motors present a single configuration of six poles.
FNote!
Since this motor is not designed to be connected directly to the power line, all the motors of this line
present a single configuration of six poles and variable electric frequency. For example, the electric
frequency of the 1500 and 3000 rpm motors is:
1500 rpm x 6 poles = 75 Hz
120
3000 rpm x 6 poles = 150 Hz
120
FNote! W21 Magnet motors can be driven by the PM with encoder and Sensorless PM control options only.
2 - Safety measures
Any service on the internal parts of the motor must be performed by qualified personnel
only, since, due to the attraction between metallic parts caused by the magnets, risk of
accident is present both in the assembly and disassembly of the motor.
People that use pacemakers cannot handle these motors. The permanent magnets can
also cause disturbances or damages to other electric equipment and components during
service.
gBefore opening the terminal box of the motor, make sure the motor shaft is not spinning.
gNever touch the motor terminals while the rotor is spinning, because, even with the inverter shut down,
risk of electric shock is present. If it is observed the possibility of the load to accelerate the motor shaft, it
is necessary to install a disconnecting device between the inverter and motor terminals.
gW21 Magnet motors feature PTC temperature sensors which must be connected to the inverter so that
the motor will be shut down in case of overheating.
In order to connect the PTC temperature sensor, it needs to connect the input X7 & COM (refer to section
3 - Inverter Installation and Connections - Standard Connection Diagram) and setting the function F2.06 to
9: External Fault Input (refer to Section 4 - Configuration of the inverter) where X7 shall be set as Normally
Closed.

3 - Inverter installation and connections
Read the WEGPM User’s Manual which is supplied with the inverter before installing, powering up or
operating the inverter.
FNote!
gInstall the inverter according to Chapter 3 - Installation and connections of the Manual.
gPrepare the drive and power up the inverter according to Chapter 4 - configuration of the inverter of the
Manual.
Note:
1.When installing DC reactor, make sure to dismantle the short connector between terminal P1 and (+).
2.NPN or PNP transistor signal can be selected as input of multi-function input terminal (X1~X7/PUL). Inverter built-in power supply
(+24V terminal) or external power supply (PLC terminal) can be chosen as bias voltage. Factory setting ‘+24V’ short connect with ‘PLC’.
3. Analog monitor output is the special output for meters such as frequency meter, current meter and voltage meter. It can’t be used for
control operations such as feedback control.
4. As there are multi pulse styles, please refer to the line connect mode description details.

5 - Solution of faults
This chapter explains the display content and measures of the inverter fault, alarm and operation fault. In addi-
tion, the poor condition caused by the inverter and motor failures and the corresponding processing measures
will be briefly described. Tuning Guide on trial use is also referred to in this chapter.
5.1 - Fault Types
Type Inverter Action When Fault Happens
Equipment Fault
When inverter detects a fault, the following conditions would happen:
●Keyboard display character showing fault content.
●Inverter output stops. Motor free slide stops.
●When function [F2.29] is 3(output fault), Y terminal outputs valid open-collector digital
output.
●When function [F2.30\F2.31] is 3(fault output), TA1-TC1, TA2-TC2 terminals output
open passive digital output.
●For faults like OL, OC, SC, OV, UL2, if [FA.22] is not 0, the inverter will restart auto-
matically after the time interval set by [FA.23].
External Fault
In certain application occasions, external related equipments fault signals are consi-
dered in the inverter control system as usage of monitoring, protection and switch con-
trol. At this time, if one multi function terminal is defined as “external fault”, and when
the external related equipments fault signals are effective, the inverter stops output and
give out alarm signal.

1 - 技术
W21 Magnet 驱动系统是由 W21 Magnet 永磁同步电机和 WEGPM 变频器组成的驱动系统。
W21 Magnet 电机具有三相定子绕组，类似于感应电动机，转子装有永磁体，而不是鼠笼式转子。永磁体
消除了在转子上所需的感应电流（励磁电流）；因此，电机在空载状态下具有极低的电流，足以弥补电气
损耗。除了励磁电流以外，W21 Magnet 也不需要滑差补偿，因为轴转速不随负载而变化。
所有 W21 Magnet 电机均为单一的六极配置。
F注意 !
由于该电机没有被设计成直接连接供电电源，该产品线的所有电机均为单一的六极配置并可变频。举个例
子，1500 rpm 转速的电机和 3000 rpm 转速的电机频率分别为：
1500 rpm x 6 极= 75 Hz
120
3000 rpm x 6 极= 150 Hz
120
F注意 ! W21 Magnet 电机仅可由 PM 带编码器和 PM 无传感器控制选项来驱动。
2 - 安全措施
任何在电机内部部件的服务必须由具备专业资质的人员操作，由于金属部件之间的磁力吸引
力，因此，无论在电机的组装和拆卸过程中均存在风险。
使用心脏起搏器的人员不得操作此类电机。
永磁体也可以在服务过程中造成干扰或损坏其他的电气设备。
g在打开电机的接线盒之前，确保电机轴处于停止状态。
g绝对禁止在转子旋转时触碰电机的接线端子, 因为即便变频器处于关机状态，触电的危险依旧存在。如果
观察到负载有可能加速电机轴的可能性，有必要在变频器和电机端子之间安装断开装置。
gW21 Magnet 电机带有 PTC 温度传感器，它必须连接到变频器上，确保电机在过热的情况下被停机。
为连接PTC 温度传感器，可将输入信号与 X7 和 COM 端口连接 （端口位置参照 第3章-变频器的安装和连
接 - 标准连接图）并设置变频器参数组 F2.06 为 9: 外部故障输入 (设置方法参照第4章-变频器的配置) ，
注意，X7的端子极性应设置为常闭，即断开有效。

如需更多关于电机安装和维护的信息，请参照随电机提供的安装维护操作手册。
