8.1.7 3RW44 in a Standard Circuit with Soft Start/Stop and Additional Slow Speed Function in both
Directions of Rotation with one Parameter Set
Note: parameterization Set the control input functions to: IN1: Motor right PS1 IN2: Motor left PS1 IN3: Slow speed mode IN4: Trip/Reset (factory setting) The slow speed parameters in parameter set 1 must be set. Motor right means rotation in line phase direction, motor left means rotation counter-clockwise to the line phase direction. Notice The slow speed function is not suitable for continuous operation. The motor can overheat at slow speed during continuous operation. Caution: risk of restart: The start command must be reset before a reset command is issued, since an automatic restart is executed when a start command is pending after the reset
command is issued. This especially applies to motor protection tripping. K1, K2, K3 = relays for contact multiplication, e.g. for 230 V AC operation: 3RS 1800-1BP00
