Speed demand En Speed reference calculation enabled.
Winder side Selection of the winding/unwinding side: 0 = up, 1 = down
W gain Setting of the speed reference gain used to saturate the loop. Parameter as a percentage
of the increasing/decreasing value of the angular speed reference.
Speed match Command of the coil “launching” phase for an automatic switching.
Spd match gain Setting of the speed reference gain during the launching phase, 100% corresponds to a
peripheral speed equal to the line speed.
Spd match acc Motor acceleration time during the launching phase, in [s].
Spd match dec Motor deceleration time in [s] if during the launching phase a stop command is given.
Spd match compl Indication of a completed launching ramp, if it is programmed on a digital output it can
be used to state that the coil can be changed.
Spd match torque Setting of the torque current during the launching and change phase. The parameter is
given as a percentage of the drive rated current.
W offset Offset setting on the speed reference for the initial phase of the winder/unwinder when
the line is stopped. The parameter is given in [rpm].
Offset acc time Setting of the ramp for the initial phase when the machine is stopped. The parameter is
given in [s]. It refers to Speed base value.
W target Parameter number where the speed reference has to be addressed to. In order to obtain
the real number to be set, it is necessary to add +2000H (8192 decimal) to the parameter
number.
1. Addressing example on the speed reference 2:
OPTION Menu
————> Torque winder
————> Speed demand
————> W target = 8235
Paragraph 10.4. “List of the high priority parameters’ shows that Speed ref 2 has the
decimal number 43. In order to obtain the value to be entered, it is necessary to add
8192 decimal (fixed offset): 8192 + 427 = 8235
W reference Monitor for the speed reference.
Jog TW enable Jog function enabled.
Jog TW speed Reference setting for Jog function. The parameter is given as a % of Line speed.
