omron — L: Protection Function

B.2 Parameter Table Default setting value is 120% when C6-01 is set to 1 (ND) and 150% when C6-01 is set to 0 (HD). Default setting value is dependent on parameter o2-04, Drive Model Selection. When enabled, the drive stops accelerating when it exceeds the value of L3-02, Stall Prevention Level. The drive decelerates after 100 ms and begins accelerating again after restoring the current level.

L6: Overtorque Detection Use L6 parameters to configure overtorque detection. L6-01 Torque Detection Selection 1 Selects the overtorque operation.

Overtorque is determined by the settings in parameters L6-02 and L6-03. The multi-function output settings (H2- 01= B and 17) are also active if programmed. 0: Disabled 1: oL3 at Speed Agree - Alarm (overtorque detection only active during Speed Agree and operation continues after detection). 2: oL3 at RUN - Alarm (overtorque detection is always active and operation continues after detection). 3: oL3 at Speed Agree - Fault (overtorque detection only active during Speed Agree and drive output will shut down on an oL3 fault). 4: oL3 at RUN - Fault (overtorque detection is always active and drive output will shut down on an oL3 fault).

0 to 4 0 O 4A1 108 L6-02 Torque Detection Level 1 Sets the overtorque detection level. 100% is equal to the motor rated current. 0 to 300 150% O 4A2 108 L6-03 Torque Detection Time 1 Sets the length of time an overtorque condition must exist before Torque Detection is triggered. 0.0 to 10.0 0.1 s O 4A3 108 L8: Hardware Protection Use L8 parameters to configure hardware protection functions. L8-01 Internal Dynamic Braking Resistor Protection Selection (ERF type) Selects the Braking resistor when using a 3% duty cycle heatsink mounted braking resistor. This parameter does not enable or disable the braking transistor of the drive. 0: Resistor overheat protection disabled 1:

Resistor overheat protection enabled 0, 1 0 O 4AD 109 L8-05 Input Phase Loss Protection Selection Selects the detection of input current phase loss, power supply voltage imbalance, or main circuit electrolytic capacitor deterioration. 0: Disabled 1: Enabled 0, 1 1 O 4B1 109 L8-10 Heatsink Cooling Fan Operation Selection Controls the heatsink cooling fan operation. 0: Fan On-Run Mode - Fan will operate only when the drive is running and for 60 seconds after stop. 1: Fan always on - Cooling fan operates whenever the drive is powered up. 0, 1 0 O 4B6 109 L8-12 Ambient Temperature Setting Used to input the ambient temperature. This value adjusts the drive oL2 detection level.

-10 to 50 30 °C O 4B8 109 L8-18 Soft CLA Selection Selects the software current limit function. Typically no adjustment is required. 0: Disabled 1: Enabled 0, 1 1 O 4BE 109 L8-35 Installation Method Selection Selects the installation type: 0: IP20/Open-Chassis Drive 1: Side-by-Side Mounting 2: NEMA 1 Type Drive 3: Finless Drive or External Heatsink Installation 0 to 3 0 O 4ECH 110 L8-38 Carrier Frequency Reduction Provides protection to the IGBTs by reducing the carrier frequency at low speeds. 0: Disabled 1: Enabled below 6 Hz 2: Enabled for the whole speed range Current ND HD 200 V Single Phase C6-02 80% of HD Carrier Frequency 400 V: 60% of HD 0 2 10 (8) 15 0 to 2 0 O 4EF 110
