7. Set parameter L3-04 = “0” or “3” to disable stall prevention during deceleration.
Set parameter L8-01 to “1” to enable overheat protection when using a heatsink-mounted braking resistor
option.
Set L8-01 = “0” for other braking resistor types.
Set parameter L3-04 = “3” to generate the shortest possible deceleration time.
Table 3.17 Braking Resistor Settings
8. Operate the system and verify the required deceleration rate is obtained during dynamic braking or stopping.
Parameter Settings
L8-01: Internal Dynamic Braking Resistor Protection Selection
0: Disabled. The drive will not provide overheat protection. Supply
separate means of overheat protection.
1: Enabled. Braking Resistor is protected from overheat.
L3-04: Stall Prevention During Deceleration
Note:Select either 0 or 3
0: Stall prevention disabled.
3: Stall prevention enabled with a braking resistor
Note: This setting cannot be used in OLV control for PM
motor.
