Setup of gain pre-adjustment protectionWhen in TroubleRelated pageRelated pageRelated pageBefore starting gain adjustment, set the following parameters based on the conditions ofuse, to assure safe operation.1) Setup of over-travel inhibit inputBy inputting the limit sensor signal to the driver, the bumping against mechanical endcan be prevented. Refer to interface specification, positive/negative direction over-travel inhibit input (POT/NOT). Set the following parameters which are related to over-travel inhibit input.Pr5.04 Setup of over-travel inhibit inputPr5.05 Sequence at over-travel inhibitP.3-38 (POT/NOT), P.4-42 (Pr5.04, Pr5.05)2) Setup of torque limitBy limiting motor maximum torque, damage caused by failure or disturbance such asbite of the machine and collision will be minimized. To apply standardized limit throughparameters, set Pr0.13 The 1st torque limit.If the torque limit setup is lower than the value required during the actual application,the following two protective features will be triggered: over-speed protection whenovershoot occurs, and excess positional deviation protection when response to thecommand delays.By allocating the torque in-limit output (TLC) of interface specification to the output sig-nal, torque limit condition can be detected externally.P.3-45 (TLC), P.4-10 (Pr0.13), P.4-47 (Pr5.21)3) Setup of over-speed protectionGenerates Err26.0 Over-speed protection when the motor speed is excessively high.Default setting is the applicable motor maximum speed [r/min] × 1.2.If your application operates below the motor maximum speed, set Pr5.13 Setup ofover-speed level by using the formula below.Pr5.13 Setup of over-speed level = Vmax × (1.2 to 1.5)Vmax: motor maximum speed [r/min] in operating conditionFactor in ( ) is margin to prevent frequent activation of over-speed protection.When running the motor at a low speed during initial adjustment stage, setup the over-speed protection by multiplying the adjusting speed by a certain margin to protect the mo-tor against possible oscillation.P.4-45 (Pr5.13)(Continued ...) |
