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 - 1000 Hz : +/- 0.003 Hz
System response time (terminals 18, 19, 27, 29, 32, 33) :  2 ms
Speed control range (open loop) 1:100 of synchronous speed
Speed accuracy (open loop) 30 - 4000 rpm: Maximum error of ±8 rpm
All control characteristics are based on a 4-pole asynchronous motor
