The 700 SERIES Digit Inverters along with Brushless AC servomotors represent our best solution for the “motion control” needs.
The speed and torque control are realized by the FOC VECTOR system with encoder feedback.
They are especially suggested when you need:
- high precision on speed and torque control
- high dynamic performances
- short response time
- Special integrated features for: positioning, processing regulation, winding.
GENERAL CHARACTERISTICS:
- Digit control by DSP microprocessor.
- Simplified start-up menu (BASIC DATA) by setting those parameters strictly useful for a quick start.
- Possibility of copying all parameters into two internal memories and restoring them onto job memory.
- Possibility of restoring the default setting of all parameters..
- Possibility of bidirectional transfer (copy / restore), through a USB port, of all the memories of parameters in an external
- EEPROM KEY available separately (cod. C411S.A).
- Software “Rowan Key Manager” for saving the EEPROM KEY parameters into a file and vice-versa.
- Standard INPUT/OUTPUT resources (digital/analog) fully programmable, including:
- 6 digital inputs, 3 relay outputs, 4 analog inputs, 4 analog outputs, 2 inputs for 125Khz line driver encoder .
- Possibility of expanding the I/O resources by including the optional drive B404S.C, having: 7 digital inputs, 5 digital static outputs, 1 input for 125Khz line driver encoder.
- Keypad can display entire parameters description, thanks to 2 lines and 16 characters; more with the remotation and customization possibility can be used directly as terminal on a panel at a side of the machine.
- Network holes managing for limitation of down-times.
- Possibility of automatic re-start after fault.
- Electrical heat protection of the inverter, the motor and the braking resistance.
- RS485 Fieldbus up to 115200 bps by MODBUS RTU.
- Optional Fieldbus: PROFIBUS DPV1 - CAN OPEN - MODBUS TCP/IP - ETHERCAT - PROFINET
THE STO SAFETY FUNCTION (Safe Torque Off)
Rowan inverters integrate the STO safety function, so that they can be used to create a PDS(SR).
The STO safety function is a function that allows you to implement an EMERGENCY RESPONSE
with safe inhibition of engine torque, in which case the engine becomes free to rotate based on its
own inertia and load (uncontrolled stop, in accordance with stop category 0 according to IEC
60204-1).
