When set to 1 - Two wire control, the motor only rotates if the FR Forward command or FR Reverse com-
mand is present. The simultaneous presence of the FR Forward and FR Reverse commands causes the
motor to stop.
The FR start mon output is enabled if the FR Forward and FR Reverse commands are not present simultaneously.
The FR reverse mon output repeats the status of the FR Reverse command.
For 2 - Three wire control the FR *stop command must be present on a digital input programmed via the FR
*stop src parameter (not present in the default condition). When set to Three wire control, the motor starts
upon receiving an impulse of not less than 50 msec on the FR Forward terminal. Once the motor has started
the command is no longer necessary on the FR Forward terminal. To reverse the direction of rotation enable
the FR Reverse command: the motor will be brought to the zero speed with the set ramp and will restart in the
opposite direction of rotation. The motor rotates in the Reverse direction for as long as the FR Reverse signal
is enabled. If the FR Reverse signal is disabled the motor rotates in the Forward direction. To stop the motor
open the FR *stop contact.
