Gemini GV6K/GT6K Command Reference
The
DPBW
command sets the bandwidth of the position loop. Higher values will increase responsiveness
and dynamic stiffness. Excessive position loop bandwidth can result in reduced stability, causing long
settling times; this is particularly true in applications with resonant mechanics.
Working with servo gains
.
•
Servo tuning process: refer to the
Hardware Installation Guide
.
•
Check the values of all active gains (
DPBW
is one of many servo gains): use
TGAIN
.
•
Creating and invoking gain sets: see
SGSET
,
SGENB
,
TGAIN

The
DPCUR
command changes the location of the cursor on the RP240 display. The RP240 lines are
numbered from top to bottom, 1 to 2. The columns are numbered left to right, 0 to 39.

The
DPHBAL
command adjusts the current amplitude of phase B with respect to phase A.
A procedure for configuring Phase Balance is provided in the
Configuration
chapter of the
Hardware
Installation Guide
.
Example
:
DPHBAL110
; sets the current amplitude of phase B to 110%
; of the current in phase A.
