9.1.7 3RW44 in a Standard Circuit with Soft Start/Stop and Additional Slow Speed Function in both
Directions of Rotation with one Parameter Set
1) For permissible main and control voltage values, refer to Technical Data, Pages 10-8 to 10-12.
Note: parameterization Set the control input functions to: IN1: Motor right PS1 IN2: Motor left PS1 IN3: Slow speed mode IN4: Trip/Reset (factory default) The slow speed parameters in Parameter Set 1 must be set. Motor right means rotation in line phase direction, motor left means rotation against 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, as an automatic restart is executed when a start command is pending after the reset command is issued. This applies to motor protection tripping in particular. K1, K2, K3 = relays for contact multiplication, e.g. for 230 V AC operation: 3RS 1800-1BP00
