L55 Torque Bias (Startup time)
L55 specifies the startup time of the torque bias.
- Data setting range: 0.00 to 1.00 (s)
Terminal command "Hold torque bias" and startup time
Setting "62" to any general-purpose, programmable input terminal (by function codes E01 to E08,
E98 and E99) assigns the H-TB command.
Turning the
H-TB
ON holds the reference torque bias; turning it OFF releases the hold.
When a run command FWD or REV is turned ON, the inverter increases the reference torque bias
value to the specified torque bias in the time length proportional to L55. Note that L55 specifies the
time length required from the start of running until the torque changes from 0 to 100% of the motor
rated torque. Once the reference torque bias value reaches the specified one, the bias setting applies.
