Description
39
Pre-exciting command
When this terminal is valid, motor pre-exciting will be
started until this terminal becomes invalid.
40
Zero out power consumption
quantity
After this command becomes valid, the power
consumption quantity of the inverter will be zeroed out.
41
Maintain power consumption
quantity
When this command is valid, current operation of the
inverter will not impact the power consumption quantity.
42
Source of upper torque limit
switches to keypad
When this command is valid, the upper limit of the torque
will be set by keypad
56
Emergency stop
When this command is valid, the motor decelerate to
emergency stop as per the time set by P01.26.
57
Motor over-temperature fault
input
Motor stops at motor over-temperature fault input.
59
FVC switches to V/F control
When this terminal is valid in stop state, switch to
SVPWM control.
60
Switch to FVC control
When this terminal is valid in stop state, switch to
closed-loop vector control.
61
PID polarity switch-over
Switching the output polarity of PID, this terminal should
be used in conjunction with P09.03
66
Zero out the counter
Zero out the position counting value
67
Pulse increase
When the terminal function is valid, the pulse input is
increased according to the P21.27 pulse speed.
68
Enable pulse
superimposition
When the pulse superimposition is enabled, pulse
increase and pulse decrease are effective.
69
Pulse decrease
When the terminal function is valid, the pulse input is
decreased according to the P21.27 pulse speed.
70
Electronic gear selection
