Danfoss FC 103 - Connection Tightening Torques

Control card, 10 V DC output
Terminal number 50
Output voltage 10.5 V ±0.5 V
Max. load 15 mA
The 10 V DC supply is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
Control characteristics
Resolution of output frequency at 0–590 Hz ± 0.003 Hz
Repeat accuracy of Precise start/stop (terminals 18, 19) ≤± 0.1 ms
System response time (terminals 18, 19, 27, 29, 32, 33) ≤ 2 ms
Speed control range (open-loop) 1:100 of synchronous speed
Speed control range (closed-loop) 1:1000 of synchronous speed
Speed accuracy (open-loop) 30–4000 rpm: error ±8 rpm
Speed accuracy (closed-loop), depending on resolution of feedback device 0–6000 rpm: error ±0.15 rpm
All control characteristics are based on a 4-pole asynchronous motor
Control card performance
Scan interval 1 ms
Control card, USB serial communication
USB standard 1.1 (full speed)
USB plug USB type B “device” plug
Connection to PC is carried out via a standard host/device USB cable.
The USB connection is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
The USB ground connection is not galvanically isolated from protection ground. Use only an isolated laptop as PC connection to
the USB connector on the adjustable frequency drive.
