Motor power P must correspond to inverter power r Cable length limits must not be exceeded. Motor cable and motor must have no shortcircuits or earth faults 4. Motor parameters must match the motor in use 5.
Value of stator resistance P must be correct 6. Motor must not be obstructed or overloaded - Increase the ramp time - Reduce the boost level OFF2 F OverVoltage - DC-link voltage r exceeds trip level P - Overvoltage can be caused either by too high main supply voltage or if motor is in regenerative mode. Regenerative mode can be cause by fast ramp downs or if the motor is driven from an active load.
Check the following: 1. Supply voltage P must lie within limits indicated on rating plate. DC-link voltage controller must be enabled P and parameterized properly. Ramp-down time P must match inertia of load. Required braking power must lie within specified limits. NOTE: Higher inertia requires longer ramp times; otherwise, apply braking resistor.
Supply must not be susceptible to temporary failures or voltage reductions. Load duty cycle must lie within specified limits. Load duty cycle must be correct 2. Trained and authorized to energize, de-energize, clear, ground and tag circuits and equipment in accordance with established safety procedures. Trained in the proper care and use of protective equipment in accordance with established safety procedures.
Trained in rendering first aid. This connection is normally used to ground the inverter. This connection is normally used to ground the motor. Use for intended purpose only The equipment may be used only for the application stated in the manual and only in conjunction with devices and components recommended and authorized by Siemens. Specific Warnings, Cautions and Notes that apply to particular activities are listed at the beginning of the relevant chapters and are repeated or supplemented at critical points throughout these sections.
Non-compliance with Warnings or failure to follow the instructions contained in this manual can result in loss of life, severe personal injury or serious damage to property. Only suitable qualified personnel should work on this equipment, and only after becoming familiar with all safety notices, installation, operation and maintenance procedures contained in this manual. The successful and safe operation of this equipment is dependent upon its proper handling, installation, operation and maintenance.
Risk of electric shock. The DC link capacitors remain charged for five minutes after power has been removed. It is not permissible to open the equipment until 5 minutes after the power has been removed. This equipment may only be used for the purpose specified by the manufacturer.
Unauthorized modifications and the use of spare parts and accessories that are not sold or recommended by the manufacturer of the equipment can cause fires, electric shocks and injuries. Suitable electronic tools should be used. Before installing and commissioning, please read these safety instructions and warnings carefully and all the warning labels attached to the equipment.
Also be sure to protect it against water rainfall and excessive temperatures see Table Only permanently-wired input power connections are allowed. When operating electrical devices, it is impossible to avoid applying hazardous voltages to certain parts of the equipment. Any disengagement of the Emergency Stop facility must not lead to uncontrolled or undefined restart.
Certain parameter settings may cause the inverter to restart automatically after an input power failure e. Wherever faults occurring in the control equipment can lead to substantial material damage or even grievous bodily injury i.
Motor parameters must be accurately configured for motor overload protection to operate correctly. This equipment is capable of providing internal motor overload protection in accordance with ULC section Refer to P and P, i 2 t is ON by default. Any defective parts or components must be replaced using parts contained in the relevant spare parts list. Disconnect the power supply before opening the equipment for access. Retain the packaging for future use.
Easy-to-release screw and snap connectors allow you to break the unit down into its component parts. You can then re-cycle these component parts, dispose of them in accordance with local requirements or return them to the manufacturer.
These components can be easily destroyed if not carefully handled. Frame Sizes A Frame Sizes B and C Frame Sizes D and E Frame Size F Frame Size A Frame Size FX Frame Size GX Frame Size D and E Frame Size F with filter The various models available cover the performance range from W to kW for constant torque CT , alternatively up to kW for variable torque VT.
This makes them reliable and versatile. A special pulse-width modulation method with selectable Pulse frequency permits quiet motor operation. Comprehensive protective functions provide excellent inverter and motor protection.
There is danger of injury when the fan is running. Do not install the inverter in an area where it is likely to be exposed to constant vibration. Mechanical strength to EN Deflection: 0. Water Take care to site the inverter away from potential water hazards, e. Avoid installing the inverter where excessive humidity and condensation may occur. The inverters can be mounted without any clearance at either side. When mounting inverters one above the other, the specified environmental conditions must not be exceeded.
Independent of this, these minimum distances must be observed. Product Videos. Explore More Product. VFD Control Panel. Control Panel. Proximity Sensor. Photoelectric Sensors. Reach Us. Does anyone have any sample ladder logic or can point me to a Siemens manual that shows how to start and stop the Siemens MicroMaster VFD?
I know that the drive has a control word but I don't know how the control word is handle in the pLC S I am writing the program in ladder. Is Siemens with profibus like Allen Bradley's Devicenet? Address and function Thanks in advance Hello, Jimdi4; I suggest you download a manual from the Siemens website www4. Do not concern yourself with the hardware part of the manual, but study chapter 5, "Commisionning".
It describes PPOx comm. The ID number of the manual is it makes search easier on the Siemens website. Start with setting the speed setpoint before starting.
