6.1.3 Signal Operation and Functions
(1) Servo on (SVON3
By turning on this signal, Servopack main circuit power drive circuit operates
according to the following conditions and the motor is applied with current.
I f = CIRCUIT OPERATES.

(2) Operation start (AS-g_
@ Operation start signal in automatic operation mode or zero-point return (homing)
mode. 5ms or more pulse width required.
@ AsT signal becomes effective when the following conditions are satisfied and
operation is started by signal rising edge.

Notes:
• Position reference not normal: when reference data exceed software overtravel
value (refer to Par. 8.3 "Parameters 40, 417).
• Speed reference not normal : when data exceed speed limit value (refer to Par.
8.3 "Parameter 46").
• The STOPsignal is active when contact is open.
In the above cases, an error occurs by turning AST signal on and operation does not
start. Instead, ERRsignal (refer to Par. 6.3.2 (3)) is output.
