The Digital Input (DI) and Digital Output (DO) have factory default settings which correspond to the various servo drive control modes. (See section 1.5). However, both the DI's and DO's can be programmed independently to meet the requirements of the users.

Detailed in Tables 3.B and 3.C are the DO and DI functions with their corresponding signal name and wiring schematic. The factory default settings of the DI and DO signals are detailed in Table 3.G and 3.H.

All of the DI's and DO's and their corresponding pin numbers are factory set and non-changeable, however, all of the assigned signals and control modes are user changeable. For Example, the factory default setting of DO5 (pins 28/27) can be assigned to DO1 (pins 7/6) and vise versa.

The following Tables 3.B and 3.C detail the functions, applicable operational modes, signal name and relevant wiring schematic of the default DI and DO signals.

			+	-
SRDY	01	ALL	7	6	SRDY is activated when the servo drive is
					ready to run. All fault and alarm conditions, if
					present, have been cleared.
					SON is activated when control power is
					applied the servo drive. The drive may or
					may not be ready to run as a fault / alarm
					condition may exist.
SON	02	Not	-	-	Servo ON (SON) is "ON" with control power
					applied to the servo drive, there may be a
		assigned
					fault condition or not. The servo is not ready
					to run. Servo ready (SRDY) is "ON" where	C5/C6/C7/C8
					the servo is ready to run, NO fault / alarm
					exists. (P2-51 should turn servo ready SRDY
					off / on)
					ZSPD is activated when the drive senses the
					motor is equal to or below the Zero Speed
					Range setting as defined in parameter P1-
ZSPD	03	ALL	5	4	38.
					For Example, at factory default ZSPD will be
					activated when the drive detects the motor
					rotating at speed at or below 10 rpm. ZSPD
					will remain activated until the motor speed
					increases above 10 RPM.
