Chapter 5 Parameter Introductions
◆This terminal is used for pulse input to the internal counter of the inverter. The highest
pulse frequency is 400 Hz. The present counting value can be saved when power off.
51: Counter clear
This terminal is used to clear the counter to zero .The terminal function is in
conjunction with Counter's trig signal input.
52: Actual Length clearing
When terminal 52 is enabled, the setting of P8.01 (actual length) will be cleared to
zero.
54: PUL: Pulse input
◆For 3004GB and below models, only multi-function input terminals X4 and X5 can
be defined as this function; for 35R5GB/37R5PB and above models ,only
multi-function input terminals X7 and X8 can be defined as this function . The input
pulse frequency can be used as frequency reference. See Parameter Group P4 for the
relationship between input pulse frequency and the reference frequency.
55: Single-phase speed measuring input
◆Only multi-function input terminals X7 and X8 can be defined as this function. See
the control circuit wiring details in section 2.5 and 2.6. The speed control accuracy is
±0.1%. Single-phase speed feedback control can be realized by using this terminal and
PG.
56～57: Speed measuring input SM1/SM2
◆For the inverter model of 3004GB and the below models, Only multi-function input
terminals X4 and X5can be defined as this function. For the inverter model of
35R5GB/37R5PB and above models, only multi-function input terminals X7 and X8
can be defined as this function. See the control circuit wiring details in section 2.5 and
2.6. The speed control accuracy is ±0.1%. Dual-phase speed feedback control can be
realized by using this terminal and PG.
P3.09 Terminal function mode setup
Range: 0～3【0】
0: 2-wire control mode 1 1: 2-wire control mode 2
2: 3-wire control mode 1-self-hold function (append any terminal of X1-X8)
3: 3-wire control mode 2-self-hold function (append any terminal of X1-X8)
Note:
◆The listed functions above are only valid when P0.04 is set to 1, 2 or 5 (terminal
control).
◆2-wire control mode 1
FWD, REV: Running at preset direction. FWD means running forward, and Rev means
running reverse. You can control the motor’s running direction by switch terminal
FWD and REV. If FWD is valid, run forward; if REV is valid and P2.26 is set to 1
(Prohibit reverse operation enabled), The inverter will stop. If P2.26 is 0 (Prohibit
reverse operation disabled), the inverter will run reverse. If FWD and REV are valid or
invalid at the same time, the inverter will stop. Terminals wiring is shown in Fig.1
