40 Chapter 5 Parameters
If traverse operation is enabled, closing the terminal can
clear the information about traverse status no matter the
drive is in auto or manual start mode. Traverse operation
continues after this terminal is disconnected. See F6.
35: external Stop command
This Stop command is valid to all control modes. When this
function is enabled, the drive will stop as specified F2.08.
36: Reserved
37: Prohibit drive from operating
If this function is enabled, the drive that is operating will
coast to stop and the drive ready to run will be prohibited to
start. This function is mainly used as safety protection.
38: Reserved
39: Clear the length information
The setting of F9.15 (length) will be cleared to zero.
40: Clear the setting of auxiliary reference frequency
This function is valid for auxiliary reference frequency
(F9.01=1, 2 and 3) to clear it to zero, so that the reference
frequency is determined solely by main reference.
41: Reset PLC state
When the drive stops in PLC mode, the memorized PLC
operating information (operating stage, operating time,
operating frequency, etc.) will be cleared.
42: clear the counter to zero
This function is to clear the counter to zero and is used in
conjunction with function 43.
43: Input signal to trigger the counter
When the setting is 43, this terminal is used to input counting
pulse signal to the internal counter of the drive. The max.
pulse frequency is 200Hz. The present counting value can
be saved at power off. See F7.33 and F7.34 for details.
44: input the signal of length
This function is only effective to multi-function input terminals
X4 and X5. The terminal is used in fixed-length control.
Length is calculated by input pulses. See F9.14~F9.19 for
details.
45: pulse frequency input
This function is effective only to multi-function input terminals
X4 and X5. The terminal is used to input pulse signal that is
used as frequency reference. Refer tp F1 parameters for the
relationship between input pulse frequency and the
reference frequency.
46: Single-phase speed measuring input
This function is effective only to multi-function input terminals
X4 and X5. See section 3.2.3 for input characteristics. 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
This function is effective only to multi-function input terminals
X4 and X5. See section 3.2.3 for input characteristics. The
EV1000 Series General Purpose Variable Speed Drive User Manual
speed control accuracy is ±0.1%. 2-phase speed feedback
control can be realized by using this terminal and PG.
Note
When the drive is in motor auto-tuning status, No. 44~47
functions of X4 are disabled automatically.
