Max. load
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
System response time (terminals 18, 19, 27, 29, 32, 33)
Speed control range (open loop)
Speed accuracy (open loop)
All control characteristics are based on a 4-pole asynchronous motor
