Technical Manual for EA350 Analog Pulse Type Servo Driver V101 8.11 P6-xx Input and output parameters Parameter functions: Set the filtering time of DI terminal. When there is strong external disturbance, to prevent such external disturbance, a filtering time can be set for the DI terminal. It means signal of DI terminal must be held for the time set by P6-00 before the driver can recognize status change of the DI terminal (OFF→ON or ON→OFF). For example, if P6-00 is set to 2, then the signal of DI terminal must be held for 2ms before the driver can recognize status change.
In case of edge trigger, if pulse signal is used, then the width of pulse signal must be greater than 2ms (in case of ideal square waves, a greater width will be actually required). See the attached figure of P6-01 Parameter functions: Set the level logic of each DI terminal and set stop. These settings will become valid upon power-on again. 8 channels of DI can be respectively set; if for some bit, bit X = 0, then external input of low level is valid; otherwise if bit X = 1, then external input of high level is valid. *: The letter B at the end of the number means the parameter value is expressed in binary, and shall be noted upon rewriting by communication.
Caution ☞ To enable corresponding terminal by means of RS485 communication, please use P6-10 parameter. (Use of this parameter may cause damage to the driver storage) For servo enable input (S-ON), disable forward driving (P-OT), and disable reverse driving (N-OT) signals, if the level logic of factory settings is changed, motor power will not be able to be turned OFF and over-travel prevention function will not act in case of signal line disconnection or other anomalies. If you are left with this choice only, please perform act confirmation to rule out safety issues. Important:
