The micro-drive solution Simple and safe operability, compact design as well as improved performance features were the focus during the development of the FR-D700 frequency inverter. A drive was created that set new standards in the field of compact drives. Improved functions and device properties such as simplified cabling thanks to spring clamps, the integrated Digital Dial with LED display, improved performance yield in the low-speed range as well as the integrated emergency stop function make the FR-D700 the new standard in the ultra compact class. The FR-D700 is especially advantageous for standard applications by virtue of its user- friendliness.
This inverter actively monitors its own functional safety. If, for example, the fan rpm decreases to 50 %, a pre-alarm is triggered. An internal measuring program monitors the ageing of the capacitors and an operating hours counter enables the operator to plan the best time for servicing. Protection and overload functions ensure trouble-free operation. The FR-D700’s OEC function helps to further optimize current and hence power consumption of the motor. The FR-D700 is designed for a service life of over 10 years. This is made possible, among other things, by high-performance heat- resistant capacitors, cooling fans with sealed bearings and special lubricating grease. The flow of cooling air comes into contact only with the heat sinks and not electronic components. This ensures that no dust or dirt can collect on the components.
Improved speed range. 150% or more motor torque is now possible at 1 Hz using General Purpose Magnetic Flux Vector control, giving a smooth open loop speed range of 60:1.
More interoperability. The D700 communications include Modbus RTU as well as Mitsubishi Electric’s own RS 485 programming protocol (supported as standard).
Remote operation. Drive I/O can be remotely operated over any supported network, regardless of what the
drive is doing.
Easy mounting. In smaller panel spaces, the D700 can be “bookshelf’ mounted without a gap in between, and DIN Rail mounting is also possible. 100kA fault-withstand rating simplifies panel construction.
Safety Stop Function. The D700 comes standard with a safety stop circuit allowing the removal of a previously required external contactor and is EN951-1 Category 3 and IEC60204-1 Stop Category 0 compliant.
RoHS compliant. Approved for installation on Europe-bound machines.
High accuracy. Analog inputs/outputs provide master/slave control.
“Maintenance free.” Intelligent fan control, fewer moving parts, more robust bus capacitors and custom-made intelligent power modules are all designed to have a 10-year operating life so that users can install the D700
and forget it.
