Ordinary mode
Stop-on-contact control
Goes into stop-on-contact control mode when both
RL and RT switch on.
Note: (RL and RT may be switched on in any order with
any time difference.)
(a) Acceleration time (Pr. 7)
(b) Deceleration time (Pr. 8)
(c) Second deceleration time (Pr. 44)
Note: The input signal terminals used depend on the Pr. 180 to Pr. 186 settings.
When both the RT and RL terminals are switched on, the inverter enters the stop-on-contact mode, in which
operation is performed at the frequency set in Pr. 6 "multi-speed setting (low speed)" independently of the
preceding speed.
