Air flow / cooling
Turbulent air speed of min. 3 m/s to achieve max. output power at max. ambient temperature.
Turbulent air speed below 3m/s and higher ambient temperature might lead to reduced output power.
(3m/s turbulent air speed is equivalent to 6,5m/s laminar air speed)
Interfaces
Digital communication MODBUS RTU RS485 (baud rate: 9.6, 19.2, 38.4, 115.2 Kbaud)
Digital communication Slave 2 x RJ12 & 2 x spring terminals
Digital communication Master 1 x RJ12 connection
Analogue In1 0-10 VDC, 100% @ 9.5 V DC +/-2%
Analogue Out1 +10 VDC
Digital In1 Start/stop with internal pull-up
Digital In2 Alarm reset
Digital Out1 Tacho: 1 pulse/revolution | Alarm/running signal
Green LED Lit: Power connected | Flashing: Active communication
Red LED Flashing: Alarm but still running | Constantly lit: Critical alarm - stop motor
Features
Technology Sinusoidal back-EMF signal controlled via FOC (Field Oriented Control)
Flying start Yes, < 30% of max. speed
