forward torque limit
set the torque limit values as a percentage of the motor rated torque.four indevidual
regions can be set.
reverse torque limit
note: torque limits can be set seperately for the 4 ways that torque can be applied: forward
torque,reverse torque,forwards generative torque,and reverse generative torque.
forward regenerative torque limit
show the relationship between each constant and output torque to set the torque limit.
reverse generative torque limit
when the torque limit function is used, the torque limit have priority and motor speed
control and compasation will be disregarded, so the accelaration/deceleration might be
lengthened and motor speed might be reduced.
protect selection for internal DB resister (type ERF)
to set the pro tection function of hardware. 0: disabled. (select 0 when a breaking resistor
is n't being used or a braking resister unit is being used.) 1:enabled. (protects the
brakins resiter from overheating.)
overheat pre-alarm level
constant l8-02 specify the detection temperature in 'C for the inverter overheating (oh)
pre-alarm function. note: an overheat pre-alarm occurs when the temperature of the
cooling fins reaches this level.
operation selection after overheat prealarm
constant l8-03 specifies the processing that will be performed when and over head prealarm
occurs. 0:decelerate to a stop in the deceleration time set in c1-02.(protection operation:
faults contact operate).1: coast to stop.(protectio operation: faults contact operate)
2:emergency stop in the emergency stop time set in the c1-09.(protection operation: fault
contacts operate)3:continues operation.(alarm:moniter display only.) note:constant l8-02
specifies the detection temperature in 'C for the overheat(oh) prealarm function. an
overheat prealarm occurs when the temperature of the cooling fins reaches this level.
constant l8-03 specifie the processing that will be performed when an over-heat (0h1)
is detected as a protection function at 105_c.
input open phase protection selection
input open-phase protection selection 0:disabled 1:enabled.(detects input power
supply open-phase, 3-phase imbalance, or deterioration of the main cicuit capacitor.)
note: this function detects changes in the main circuit dc voltage which indicate a power
supple open phase,large imbalance in the power supply voltage, or deterioration of the main
