15.2 Stop-on-contact control
Setting the stop-on-contact control
• Make sure that the inverter is in External or Network operation mode. (Refer to
• Select either Real sensorless vector control (speed control) or Advanced magnetic flux vector control.
• Set "1 or 11" in
Pr.270 Stop-on-contact control selection
.
• Set the output frequency for stop-on-contact control in
Pr.6 Multi-speed setting (low speed)
.
Set the frequency as low as possible (about 2 Hz). If a frequency higher than 30 Hz is set, it operates with 30 Hz.
• When both the RT and RL signals are switched ON, the inverter enters the stop-on-contact control, and operation is
performed at the frequency set in
Pr.6
independently of the preceding speed.
• Setting
Pr.270
= "11" disables stall prevention stop (E.OLT) during stop-on-contact control (with both RL and RT signals
ON).
NOTE
• By increasing the
Pr.275
setting, the low-speed (stop-on-contact) torque increases, but overcurrent fault (E.OC[]) may occur
or the machine may oscillate in stop-on-contact status.
• The stop-on-contact function is different from the servo-lock function, and if used to stop or hold a load for an extended period,
this function can cause the motor to overheat. After a stop, immediately switch to a mechanical brake to hold the load.
• Under the following operating conditions, the stop-on-contact function is invalid:
PU operation (
Pr.79
), JOG operation (JOG signal), PU + External operation (
Pr.79
), PID control function operation (
Pr.128
),
Remote setting function operation (
Pr.59
), Automatic acceleration/deceleration operation (
Pr.292
), Start time tuning
Function switching of stop-on-contact control selection
Set frequency and validity of the stop-on-contact control (Pr.270 = "1 or
11")
• The following table lists the frequencies set when the input terminals (RH, RM, RL, RT, JOG) are selected together.
• Stop-on-contact control is disabled when remote setting function is selected (
Pr.59
= 1 to 3).
