Drive intended for use over a range of motor sizes. Internal motor overload protection
level is adjustable:
The internal motor protection is parameterised via the IDN P-0-0062 “Thermal motor model”,
based on the value of the IDN S-0-0111 “Motor continuous stall current”. The IDN P-0-0062
“Time constant” is specified by the motor manufacturer and must be entered here. The IDN
P-0-0062 “Warning limit” (Default) is responsible for deciding when a warning is to be
generated. The IDN P-0-0062 “Error limit” (Default) is responsible for deciding when the
motor is to be switched off. The default values take into account the specific characteristics
of the servomotors.
In Canada use only in combination with unit AX2090-TS50, manufactured
3.4 Electrical isolation according to EN 50178 / VDE 160
The power section (motor connection, DC link connection and mains connection) and the
control unit are doubly insulated against each other, so that safe protection against
accidental contact is ensured at all terminals of the control unit without additional measures.
The air and creepage distances also meet the requirements of the above standard.
