09 PLC Program Running: terminal output is activated when the PLC program is
running.
10 PLC Program Step Completed: terminal output is activated for 0.5 sec. when each
multi-step speed is attained.
11 PLC Program completed: terminal output is activated for 0.5 sec. when the PLC
program cycle has completed.
12 PLC Program Operation Paused: terminal output is activated when PLC operation is
paused.
13 Top Count Value Attained: terminal output is activated when counter reaches the Top
Count Value. See diagram for Pr.38 to Pr.42=18.
14 Preliminary Count Value Attained: terminal output is activated when counter reaches
the Preliminary Count Value. See diagram for Pr.38 to Pr.42=18.
15 Warning (PID feedback loss, communication error): the contact will be “close” when
PID feedback loss or communication is error.
16 Below the Desired Frequency: the contact will be “close” when output frequency is
less than desired frequency.
17 PID supervision: the contact will be “close” when PID offset exceeds the setting of
P126 and P127.
18 Over voltage supervision: the contact will be “close” before over voltage. It will be
activated at 370Vdc in 230V series and at 740Vdc in 460 series.
19 Over Heat supervision: the contact will be “close” before 90
°
C.
20 Over Current stall supervision: the contact will be “close” before exceeding the
setting of P26/P27.
21 Over voltage stall supervision: the contact will be “close” before exceeding the
setting of P25.
22 Forward command: the contact will be “close” with forward command.
23 Reverse command: the contact will be “close” with reverse command.
24 Zero Speed (Includes Drive Stop): the contact will be “close” when the setting
frequency is less than min. frequency or drive stop.
