4. WIRING
GA7200 has been programmed to operate from the digital operator when shipped from the factory.
Therefore, just connecting the main circuit power enables drive operation.
Note: When external signals or external devices and digital operator are used, refer to Section 7,
“CONSTANTS/FUNCTION LIST”, in this manual.

When V/f pattern is selected to be linear, set the same value for Cn-07 and
Cn-05. (Cn-06 setting is disregarded). Refer to pages 67, 68 and 69 for V/f

6.2 ACCEL/DECEL TIME SETTING
bn-01 to -04 (Sn-06, Sn-15 to -18)
Accel/decel time can be changed in DRIVE mode during running.
• Acceleration and deceleration time each has two set values. When “ accel/decel time
change” is selected (7 is set in Sn-15, Sn-16, Sn-17 or Sn-18) as a multi-function terminal
function, the values set in bn-03 and-04 become effective.
• S-curve characteristics of soft start can be selected in the 1-and 2-digits of Sn-06.
(Example) When S-curve not used, accel and decel times are set with
bn-01 through bn-04.
bn- Set Value
Accel Time 1 (bn-01) 5 seconds
Decel Time 1 (bn-02) 8 seconds
