Technical Manual for EA350 Analog Pulse Type Servo Driver V101 The time constant for pulse input filtering T f shall meet: T f ≤ (20%~25%) T min If the maximum frequency of the input pulse signal (or minimum pulse width) is known, the recommended filtering time parameter is shown in the following table: Parameter functions: Select which external DI signal is used to clear deviation. P1-16=0 : Clear through P-CLR rising edge P1-16=1 : Clear through P-CLR low level P1-16=2 : Clear through P-CLR high level P1-16=3 : Clear through P-CLR falling edge Caution ☞ When the servo activation is OFF or an alarm occurs, the position deviation will be automatically cleared. Parameter functions:
Set the warning threshold for the position following deviation. When the position deviation reaches or goes beyond the set value, warning signal for too high position following deviation will be output. The motor continues running, the LED monitor displays , and output of the DO terminal defined as WARN is valid. Once the position deviation falls below the set value, the warning will be automatically cancelled. Parameter functions: Set the alarm threshold for the position following deviation. When the position deviation reaches or goes beyond corresponding set value, alarm signal for too high position following deviation will be output.
The motor stops running, the LED monitor displays , and it is defined as valid output of the ALM DO terminal. Caution ☞ 1. When P1-18=0, position following deviation warnings will be shielded; when P1-20=0, alarms for too high position deviation will be shielded. 2. The default setting unit is a command unit, but the encoder unit can be changed via P8-18 bit 3. When the encoder unit is used, it is required to set a proper value based on the encoder resolution, so as to avoid frequent alarms as a result of a too small set value. Parameter functions: Select the condition for valid output of positioning completion signal (defined as the DO terminal of COIN). P1-22=0:
The absolute value of position deviation is smaller than P1-24.
