Power Supply and Energy Savings
Powering this motor is easy since it only requires connection of the main voltage of 3x400 VAC through the M23 connectors. Control voltage for the encoder and microprocessor circuitry is 24VDC: In an emergency-stop situation, where an approved relay has cut-off the main power, encoder position and other values are maintained by this control voltage. Furthermore highly effective switching technology is used to ensure low heat generation resulting in appreciable energy savings.
One of the big advantages of using the integrated MACmotors is that you don't need to install a separate servo driver or controller in a control cabinet. This gives you many subsequent advantages: Space savings in your control cabinet, saving of expensive motor and encoder cables, saving time and money for cabling, noise is minimized due to internal cabling and also installation errors between driver and motor are eliminated.
In addition, service is much easier, since the motor and controller can be replaced as a single integrated unit. Hence downtime is minimized and production is maximized.
MAC motor® has everything built-in including motor, encoder, drive electronics, control electronics with ePLC™ and optional Ethernet or CAN bus integrated into one compact unit. All major industrial Ethernet protocols like Profinet, EtherNet/IP, EtherCAT, SERCOS, ModbusTCP/UDP and Powerlink are available.
Options include absolute multiturn encoders and STO (safe torque off, SIL3).
When using JVL’s industrial Ethernet you will gain a unique feature: using JVL’s universal software MacTalk® you can change between the different Ethernet protocols just by making a firmware update—it is free-of-charge and you can do it as many times as you like! Choose between Profinet, EtherNet/IP, SERCOS, EtherCAT, Powerlink and ModbusTCP/UDP.
modules have built-in Ethernet-switch making cabling easy: you can daisy-chain
Ethernet cables from motor-to-motor. Function blocks (FB) for Siemens PLCs and
Add-On-Instruction (AOI) for Rockwell Allen Bradley ControlLogix PLCs are
available for download. Additionally, each motor can be equipped with an
IO Junction Box for collecting sensor inputs or trigger outputs.
In stand-alone applications you will undoubtedly like our graphical
programming environment ePLC™. Writing embedded PLC programs is very easy and
can be done even by end-users. You do not have to be an experienced PLC
programmer to make ePLC™ programs: the icon-based graphical programming
environment does the job for you. Just click on the command icon you want and
the program line is created for you. Programming is similar for all integrated
motor families: QuickStep®, ServoStep™ and MAC motor®. No matter the number of
I/O points in the actual motor, each digital input and output and analog input
can be used in the program: you can query single or multiple input conditions
and branch accordingly to other parts of your program. Motion commands are
available with different kinds of relative or absolute movements. Jumps and IF
commands, timers and other functions are also available as well as register
calculations. All registers and parameters in the motor can be accessed and
most can be changed if required.
Connect a suitable color touch operator panel (HMI) and the operators can
key-in values and parameters to the motor as well as monitor operations.
