Pos Trim Mode
Selects how to adjust output of the position controller.

(0, 1)
0: Constant
Position controller output does not depend on the speed level of the master.
1: Speed Prop
Position controller output is directly proportional to the speed level of the master.
Example: When EA-04 is set to 60 Hz, SA-56 is set to 10%, and position controller output is
10%:
• SA-55 = 0
The PI output amount added to the frequency reference is 60 Hz × 10% = 6 Hz, regardless of
the speed level of the master.
• SA-55 = 1
① When the slave frequency reference (30 Hz) is larger than 6 Hz (E1-04 (60 Hz) × SA-56
(10%)):
② When the slave frequency reference is smaller than 6 Hz (E1-04 (60 Hz) × SA-56
(10%)):
Position controller output after adjustment =
E1-04 × Position controller output (10%) × SA-56 (10%) = 0.6 Hz
Position controller output is limited by SA-56.
