64 Chapter 5 Parameter Introductions
The preset close-loop references in Table 5-10 can be
selected by the different On/Off combinations of
terminals 1~3.
33: Start traverse operation
When the traverse operation is set to "manual start", the
traverse function can be enabled if this terminal is
enabled, see Group F6 parameters for details.
34: Reset the traverse operating status
If traverse operation is enabled, switching on this
terminal can clear the memorized information about
traverse operation no matter the drive is in auto start or
manual start mode. Traverse operation restarts after this
terminal is disconnected. See group F6 parameters.
35: external stopping command
This stopping command is active in all control modes.
When terminal 35 is enabled, the drive will stop in the
mode defined in F2.08.
36: Reserved
37: disabling the drive's operation
If terminal 37 is enabled, the drive that is operating will
coast to stop and is prohibited to restart. This function is
mainly used in application with requirements of safety
protection.
38: Reserved
39: Clear the length information
When terminal 39 is enabled, the setting (length) of
F9.15 will be cleared to zero.
40: Clear the setting of auxiliary reference frequency
This function is only active for auxiliary reference
frequency (F9.01=1, 2 and 3). When terminal 40 is
enabled, the auxiliary frequency is cleared to zero and
the reference is determined by main reference
frequency.
41: Reset the stopping status of PLC operation
In stopping status of PLC operation, the memorized PLC
operating information (operating stage, operating time,
operating frequency, etc.) will be cleared when this
terminal is enabled. See Group F4 parameters.
42: clearing the counter to zero
When the setting is 42, this terminal is used to clear the
counter to zero in conjunction with terminal 43.
43: inputting triggering signal to counter
When the setting is 43, this terminal is used to input
pulse signal to the internal counter of the drive. The
highest pulse frequency is 200Hz. The present counting
value can be saved at power off. See F7.33 and F7.34
for details.
44: inputting counting value of length
EV2000 Series Universal Variable Speed Drive User Manual
Only multi-function input terminals X7 and X8 can be
used for this function. The terminal is used in
fixed-length control and calculating the length via pulses.
See F9.14~F9.19 for details.
45: inputting pulse signal
Only multi-function input terminals X7 and X8 can be
used as this function. The terminal is used to input pulse
signal as frequency reference. See Group F1
parameters for the relationship between input pulse
frequency and the reference frequency.
46: Single-phase speed measuring input
Only multi-function input terminals X7 and X8 can be
used as this function. See section 3.3.2. The speed
control accuracy is ± 0.1%. Single-phase speed
feedback control can be realized by using this terminal
and PG.
47: Speed measuring input SM1
48: Speed measuring input SM2
Only multi-function input terminals X7 and X8 can be
used as this function. See section 3.3.2. The speed
control accuracy is ± 0.1%. Dual-phase speed feedback
control can be realized by using this terminal and PG.
Note:
When the drive is performing motor auto-tuning, No. 44~47
functions of X7 are disabled automatically.
