(1) A synchronization loss occurs when the D/A converter module cannot accept the inter-module synchronization cycle.
(2) When the D/A converter module did not accept the inter-module synchronization cycle at the timing when the inter-module synchronization cycle was
supposed to be accepted, an inter-module synchronization signal error (error code: 2610H) occurs. The analog output value differs depending on the setting
of the analog output HOLD/CLEAR function as shown below.
When HOLD is set, analog output value is held.
When CLEAR is set, the offset value is output in analog.
When a synchronization loss has occurred, the module may be affected by noise. Check and adjust the cable
wiring and the installation environment of the programmable controllers, and restart the system. If the error
reoccurs even after the adjustment, the possible cause is a failure of the module. Please consult your local
Mitsubishi representative.
