0: Disabled. RTS is always on.
1: Enabled. RTS turns on only when sending.
All Modes
Sets the time required to detect a communications error. Adjustment may be needed when
networking several drives.
All Modes
0: 0.1 V units
1: 1 V units
All Modes
0: Drive requires an Enter command before accepting any changes to parameter settings.
1: Parameter changes are activated immediately without the Enter command.
Description
All Modes
0: Disabled
1: General purpose motor (standard fan cooled)
2: Drive dedicated motor with a speed range of 1:10
3: Vector motor with a speed range of 1:100
5: PM motor with constant torque characteristics
All Modes
Sets the motor thermal overload protection (oL1) time.
All Modes
Sets operation when the motor temperature analog input (H3-02 or H3-10 = E) exceeds the oH3
alarm level.
0: Ramp to stop
1: Coast to stop
2: Emergency Stop (Fast Stop) (decelerate to stop using the deceleration time in C1-09)
3: Alarm only ("oH3" will flash)
All Modes
Sets stopping method when the motor temperature analog input (H3-02 or H3-10 = E) exceeds
the oH4 fault level.
0: Ramp to stop
1: Coast to stop
2: Emergency Stop (Fast Stop) (decelerate to stop using the deceleration time in C1-09)
All Modes
Adjusts the filter for the motor temperature analog input (H3-02 or H3-10 = E).
