GSK DA98A - Adjustment

DA98A AC Servo Drive Unit User Manual
（3） Set control mode (parameter No.4) for JOG mode (for 3).
（4） Switch on the main power.
（5） If there is no alarm or any abnormality occurring, set servo enable (SON) for ON,
and the motor is excited for zero speed.
（6） Enter JOG mode by pressing keys, the prompt of it is “J”, and the unit is r/min.
When the system is in speed control mode, the speed value and direction are
defined by parameter No.21, pressing ↑ keys, the motor runs by the specified
speed and direction; pressing ↓ keys for the reverse running.
C： Position mode
（1） Connect CN1 to make input control signal: the servo enable (SON) is set for OFF,
CCW drive stop（FSTP）for ON, CW drive stop（RSTP）for ON.
（2） Switch on the control circuit power (main power is off), AC servo drive unit
monitor is turned on. If an alarm is issued, check the connection.
（3） Set control mode (parameter No.4) for position mode (for 0). Set parameter
No.14 by controller output signal and set a proper electronic gear ratio.
（4） Switch on the main power.
（5） If there is no alarm or any abnormality occurring, set servo enable (SON) for ON,
and the motor is excited for zero speed.
（6） Make the position controller to output signal to the CN16, 18, 7, 19 terminals to
run the motor by instructions.
D： Speed mode
（1） Connect CN1 to make input control signal: the servo enable (SON), speed
selection 1 (SC1), speed selection 2 (SC2) set for OFF, CCW drive stop（FSTP）
for ON, CW drive stop（RSTP）for ON.
（2） Switch on the control circuit power (main power is off), AC servo drive unit
monitor is turned on. If an alarm is issued, check the connection.
（3） Set control mode (parameter No.4) for Speed mode (for 1). Then set speed
parameter No.24～27 by requirement.
（4） Switch on the main power.
（5） If there is no alarm or any abnormality occurring, set servo enable (SON) for ON,
and the motor is excited for internal speed 1.
（6） Change the input signal SC1, SC2 mode to make the motor run by a specified
speed.
7.3 Adjustment
z Ensure the parameters to be correct before starting to protect against
unexpected accident caused by mistaken parameter setting.
z Debug the system in dry run mode prior to the loading debugging.
Note
1） Primary gain adjustment
z Speed control
（1） [Speed proportional gain] (parameter No.5) Its setting value should be set as large
as possible without oscillation occurring. Generally, the bigger the load inertia is, the
larger the setting value of < speed proportional gain> is.
（2） [Speed integral time constant] (parameter No.6) Its setting value should be set as
big as possible according to the given conditions. If it is too big, the response will be
quick but that will result oscillation. So set a bigger value if no oscillation occurs.
[Speed integral time constant] If its value is too small, the speed will be greatly
