2-30Servo-on signal accept timing on power-upCaution• The above chart shows the timing from AC power-ON to command input.• Activate the external command input according to the above timing chart.*1. In this term Servo-ON input (SRV-ON) turns ON as a hard ware, but operation com-mand can not be received.*2. S-RDY output will turn on when both conditions are met, initialization of micro com-puter has been completed and the main power has been turned on.*3. After Internal control power supply , protective functions are active from approx. 1.5sec after the start of initializing microcomputer. Please set the signals, especially forprotective function, for example over-travel inhibit input (POT, NOT) or external scaleinput, so as to decide their logic until this term.The lapse time can be changed with Pr6.18 Wait time after power-up.Servo-Ready output(S-RDY)Servo-ON input(SRV-ON)External brakerelease output(BRK-OFF)output Tr OFF output Tr ONinput coupler ONinput coupler OFFControlpower supply(L1C,L2C)Internal controlpower supplyAction ofdriver CPUMainpower supply(L1,L2,L3)DynamicbrakeMotorenergizationPosition/Speed/Torque command10ms or longer*210ms or longer*2OFFOFFONreset (initialization) usually operationOFF ONoutput Tr OFF (brake engaged) ON(brake released)releasedengagednot-energized energizedNo command entry Commandentry100ms or longer*1approx.2sapprox.100 to 300 msapprox.1.5sestablishedapprox.60msapprox.2msapprox.4ms0ms or longer0s or longer*32Preparation10.
