Initialize the Regulator
Note:
Perform this procedure with
the motor uncoupled from the
load.
CAUTION
To prevent ignition of hazard-
ous atmospheres, all of motor
and encoder covers are to be
tightly closed and all screws in
place when unit in operation.
Failure to observe this precau-
tion could result in damage to,
or destruction of the equip-
ment.
The HR2000 controller contains
non-volatile, read-write memory
(EEPROM). This memory provides
the ability to operate a variety of
motor and encoder designs by
storing the default value of the
drive parameters listed in Table
4-1. The HR2000 7 1/2 through 15
HP controllers are initialized at the
factory to INIT3. If the controller is
being installed for the first time
from the factory and the motor you
are using has the pole/RPM and
encoder characteristics for INIT3
per Table 4-1, initializing the
regulator is not necessary (
Note:
If the motor has a speed of 1750
RPM, INIT selections are still
valid). The preferred INIT
selections for 4, 6, and 8 pole
motors are listed in Table 4-1. If
you are unsure of the motor’s
design either obtain the data from
the nameplate or refer to Table 4-2.
