5.7 Power-Up Sequence
Upon powering up, the SERVOSTAR performs a series of self-
tests. If the status display illuminates a solid number, no errors
were found and the EEPROM has loaded its variable parameters
(or loaded default values in case of invalid EEPROM data) into
RAM. The Remote Enable switch on the I/O connector (C3) may
now be energized, thus enabling the servo loops.
5.8 Enabling the System
The drive enable logic is based on the following variable switches
and flags:
ACTIVE: This is the overall readiness flag indicating the
enable/disable state of the drive. If high (1), the drive is
enabled and power is being applied to motor. The
following equation must hold true for ACTIVE to go high:
ACTIVE = (READY) AND (REMOTE) AND (DIPEN)
where READY = (DRIVEOK) AND (SWEN)
READY: flag that indicates the drive is free of faults and ready to
hardware enable
DRIVEOK: switch indicates the status of the drive faults.
SWEN: switch indicates the status of the software enable (EN or
DIS).
REMOTE: switch indicates the status of the hardware Remote
Enable line on the C3 connector.
DIPEN: switch indicates the state of the DIP enable/disable switch

If the drive will not enable, you can check the state of the switches
and flags by clicking the Status button in the upper right-hand
corner of the Main
MOTIONLINK screen. If using a terminal, you
can query the drive for the value stored in the STATUS variable
(refer to VarCom Reference Guide for an explanation on STATUS
parameters). The status display indicates an enabled drive when
the decimal point is illuminated solid.
