6-10 Other Functions

The following description provides information on the other functions and parameter set-
tings of the Inverter.
Refer to Section 7 Communications for parameters used for communications.

6-10-1 Digital Operator Disconnection Error Detection

• This parameter setting is to select whether or not to detect Digital Operator connection errors.
n010
Operation Selection at Digital
Operator Interruption
Setting 0, 1
range
Set Values
Value
0 The Digital Operator connection error is not detected (Nonfatal error)
1 The Digital Operator connection error is detected (Error output and the Inverter coasts to a
stop)

6-10-2 Motor Protection Functions (n037 and n038)

• This parameter setting is for motor overload detection (OL1).
n037
Motor Protection Characteristics
Setting 0 to 2
range
Set Values
Value
0 Protection characteristics for general-purpose induction motors
1 Protection characteristics for Inverter-dedicated motors
2 No protection
• This parameter is used to set the electric thermal characteristics of the motor to be connected.
• Set the parameter according to the motor.
• If a single Inverter is connected to more than one motor, set the parameter to 2 for no protection. The
parameter is also disabled by setting n036 for rated motor current to 0.0. Provide overload protection
for each motor by setting up, for example, thermal relays.
