Technical Manual for EA350 Analog Pulse Type Servo Driver V101 There are two pre-requisites as given below for this function to be enabled: ➢ The absolute value of the speed command corresponding to the input analog voltage, upon processing of the dead zone and hysteresis, is less than P2-07; ➢ The DI terminal where the driver is defined as the zero position fixation signal ZCLAMP is valid. With the pre-requisites above fulfilled, the servo will toggle to position mode from speed mode automatically so that the motor will be locked in the scope specified by P1-24 at that position and will return to the locking position even if there is an external force.
Once the speed command is greater than P2-07, it will return to speed mode and follow the commands for running immediately despite of the status of the ZCLAMP termina. 1. This function is always valid in speed mode. 2. During position locking, if the motor shaft is rotated by an external force that reaches or exceeds the rated torque of the motor and persists, the driver might be subject to motor overload, overcurrent and other alarms.
