26,27: Acc. / Dec. time choose terminals 1, 2.
• Deceleration time priority: Terminal 26, 27 function determine the deceleration time > F03.09, F03.10
deceleration time is determined.
• Through the deceleration time terminals 1, 2, logical combination, can realize deceleration time 1 - 4
choices. See the table below.
• Set 2 deceleration time terminal function, can realize the choice of four groups of deceleration time.
• Set a deceleration time terminal function, can realize the choice of 2 groups of deceleration time.
Acc. / Dec. terminal 2 (No 27) Acc. / Dec. terminal 1(No 26) Acc. and Dec. time selection
0 0 Acc. and Dec. time 1
0 1 Acc. and Dec. time 2
1 0 Acc. and Dec. time 3
1 1 Acc. and Dec. time 4
41,42: Free down normally open / closed input.
• Frequency converter receiving terminal command, immediately put an end to the output, load stop
freely according to the mechanical inertia.
44,45: The external input fault normally open / closed.
• Fault signal has two kinds of input mode whichare normally open or normally closed, frequency
converter can detect peripheral equipment fault signal via controlling the terminals.
• After receiving an external fault signal, converter will stop freely down, at the same time, display external
equipment failure (E0024).
46: External reset input.
• When the fault alarm is occurred in inverter, this DI terminal can reset fault.
50: Counter reset signal input.
• 51 function should be used together to reset converter built-in counter.
51: Counter trigger signal input.
• Built-in counter counts pulse input port, when power off, the current count valuecan be stored.
• The highest frequency pulse: 200Hz. Specific see F15.37, F15.38.
53: Pulse frequency input (DI4).
• DI4 terminal can receive the pulse signal as a frequency setting, the relationship between input pulse
frequency and the set frequency see F05.01 - F05.04.
Terminal UP / DOWN of the rate of acceleration and deceleration
Define DI terminals as the UP / DN terminals (17/18 function), modified chaneing rate of set frequency.
Number of terminal detection filter
Delay, confirm DI terminal signals to prevent DI terminal misoperation.
