6. CURRENT REGULATOR SELF

TUNE

Per the setup in the previous section, a current regulator
self tune can now be executed from the keypad or PC.

The setting of parameter [main commands] must be =
digital, this is the default setting.

This parameter can be found under the menus:

START UP
Main commands

CONFIGURATION
Main commands

The terminal board inputs 12, 13, 14, and 15 must then
be connected to TB 19 (24 VDC), either through
jumpers, switches, or contacts.

It is recommended to have a switch wired from terminal
input 12 to 19 that is readily accessible to the user, so
under the drive can be stopped quickly during
commissioning.

The field current will be automatically set to zero during
the current reg self tune, and returned to its normal
setting when complete.

START UP

Press ENT.

Press the + key to select ON, press ENT

The drive enable light will not turn on, and the
enable parameter will still show disabled.

This is normal operation for the drive with the
default setting of parameter STOP CONTROL.

Press the green START button on the keypad.

Autotuning can take a few minutes. For 4 Quadrant
regenerative drives, the torque + and torque - will flash
alternately during the test.

For 2 Quadrant non regenerative drives, only the torque
+ will light during the test.

When the self tune is complete , and only when the test
is complete, the drive will automatically set the
parameter [START UP\ Cur reg self tune] = OFF, enable
and start commands will be turned off.

The results of this test are temporarily stored in
[CURRENT REGULAT \ Arm resistance], and
[CURRENT REGULAT \ Arm inductance]

The motor must NOT be allowed to rotate during this
test. If the motor shaft moves during this test, the shaft
must be physically locked in place.

After completion of the self tune, save the parameters.

This screen shows the digital input status on the top line and
output status on the bottom line. If a number is shown, the
status is ON for the digital inputs and outputs.

E is Enable input ( TB 12) , S is the start input ( TB 13), and
F is the Fast stop input (TB 14).

Loss of the External fault input (TB 15) lights the red alarm
LED. This example shows a default configuration, where TB
12, 13, and 14 are tied to + 24, and digital outputs 3-8 are high
( the signals are high even though there may not be a TBO
card).

To execute the self tune the top line must have ESF
showing and there can not be any alarms. Check the
hardware interlocking.
