Line Speed Value for Motor 1-n (Key-to-line Mode)
Line speed value for motor 1-n consists of additional values in the
transmission data block. They need not be set by the master. This data is
required only for motors working in key-to-line mode.
The range of values extends from 1.0 to 100.0 %, and the transmission data
must always be multiplied by a factor of 10 for transmission.
Line speed value for motor 1-n set to ”0.0” (zero) is interpreted as No speed
setpoint.
NOTE: Line speed value for motor 1−n is processed by the Nordson melter
for every transmission data block, regardless of what was entered by
Command.
In key-to-line the pump speed is regulated by Line speed value for motor
1−n. Every motor works with its own line speed signal.
The parameters Line speed for min./max. pump speed and
Min. / Max. pump speed apply to every motor.
