Flow command: 0~ Max flow is corresponding to 0~10V, set value to FA22 and FA 21.
Set FA18 by pressure sensor specification.
Feedback base pressure of pressure sensor detection: under no pressure and no flow state, test AI2/GND
voltage and set it to FA19.
(2)
Fb16, Fb17, Fb18 is corresonding to AI1, AI2, AI3 monitor value separately. When testing
analog
, user
may set monitor value to FA16, FA17, FA19, FA21, FA22.
Note: FA16
～
FA22 must be modified in stopped status.
(3)
Servo control board must have switch code SW1 to input 0~20 mA current, or else, user must connect a
500/1w resistor in parallel with analog input interface to change 0~20 mA into 0~10V signal.
(4)
Some moulding machines flow and pressure signal is 0~1A current, User may select optional card
Z2A3IQ01 to convert the signal into 0~10V.
6.4 Max pressure setting
Set Max system pressure to FA12.
6.5 FA23, F114, F115 setting
(1) Set accurate value to FA23 to ensure required max pressure for moulding machine.
Do not set FA23 too large, or servo dirve is easy to be damaged.
(2) If motor rated power is not manufacture value, prolong acceleration/deceleration time F114 and F115
properly, at least prolong 0.015s.
6.6 Closed-loop operation
