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
4: PM motor with variable torque
5: PM motor with constant torque control
6: General purpose motor (50 Hz)
The drive may not be able to provide protection when using multiple motors,
even if overload is enabled in L1-01. Set L1-01 to 0 and install separate thermal
relays to each motor.
All Modes
Sets the motor thermal overload protection (oL1) time.
All Modes
Sets operation when the motor temperature analog input (H3-02, H3-06, or
H3-10 = E) exceeds the oH3 alarm level.
0: Ramp to stop
1: Coast to stop
2: 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,
H3-06, or H3-10 = E) exceeds the oH4 fault level.
0: Ramp to stop
1: Coast to stop
2: 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, H3-06, or
H3-10 = E).
All Modes
0: Disabled
1: Enabled
All Modes
Sets the input selection for Motor #1 Thermistor.
0: Disabled
1: Thermistor input by Analog Input
2: Thermistor input by special Thermistor Input
All Modes
Sets the range of the Motor #1 oH5 trip level.
All Modes
Sets the input selection for Motor #2 Thermistor.
0: Disabled
1: Thermistor input by Analog Input
2: Thermistor input by special Thermistor Input
All Modes
Sets the range of the Motor #2 oH5 trip level.
