Mitsubishi Electric MELSEC iQ-F Series FX5 User Manual page 150

• To perform the speed-position switching control (ABS mode), the following conditions must be satisfied.
(1) "[Pr.1] Unit setting" is "2: Degree"
(2) The software stroke limit function is disabled (Upper limit value = Lower limit value)
(3) "[Pr.21] Current feed value during speed control" is "1: Update current feed value".
(4) If the settings range of "[Da.6] Positioning address/travel amount" is 0 to 359.99999 (degrees) or outside the range 0 to 359.99999 (degrees), an outside
address range (Error code: 1A31H) error will occur at startup.
(5) "[Pr.150] Speed-position function selection" is "2: speed-position switching control (ABS mode)".
• If (1) to (3) are not satisfied when (5) above is enabled, when "[Cd.190] PLC READY signal" is turned OFF→ON, a speed-
position function error (Error code: 1AAEH) will occur.
• The operation does not stop immediately at the positioning address when the positioning target reaches the positioning
address during the deceleration even if the automatic deceleration is started after Speed-position switching signal is input.
To decelerate automatically, the positioning target stops at the positioning address after the rotation is performed for N (N:
natural number) times. In the following example, the positioning target passes the positioning address twice when the
deceleration is performed in the dot-line path. Thus, the deceleration stop is performed to stop at the positioning address at
the third time.
