(SIMOVERT MASTERDRIVES Vector Control)
Prerequisites
Start-up steps
4-4
♦ The converter output terminals (U2/T1, V2/T2, W2/T3) of the
operating converter and the synchronizing converter are connected
up.
♦ The standard start-up procedure for the converter has been
completed.
♦ Disconnect the power supply.
♦ Insert the TSY and screw it to the electronics box. The slot options
are listed in Section 3.
♦ Make the connection between the TSY of the operating converter
(-X111:11, 12) and the TSY of the synchronizing converter
(-X111:13, 14); ensure that the screen is connected at both ends
(refer to Figs. 4 and 5).
♦ Connect up the binary inputs and outputs on the TSY of the
synchronizing converter as required. Both the status bits
"synchronism reached" and "synchronizing error" can be output at
the binary outputs for the purpose of changeover control (see Table
3 and Figs. 2 and 3). The synchronizing error message is set in
addition to the synchronism signal if an inadmissible phase deviation
occurs after synchronism had been reached. The two status bits are
reset only when synchronization is cancelled or by an OFF
command.
♦ Close the front panels and switch on the power supply.
♦ Set the V/f control mode for textile applications (P100 = 2) on the
operating and synchronizing converters
♦ Parameterize the binary inputs and outputs on the TSY of the
synchronizing converter to match the connections above (see Table
3 or check parameterization).
♦ Parameterize identical characteristics, direction of rotation and
frequency setpoints on the operating and synchronizing converters
(see SIMOVERT MASTERDRIVES Instruction Manual, Section
"Parameterizing steps"). The maximum frequency of the
synchronizing converter must be set to about 1 Hz higher than that
of the operating converter.
♦ Adjust synchronization parameters P529 to P532 on the
synchronizing converter as required.
P529: Maximum permissible frequency deviation prior to
synchronization
P530: Reference phase shift for synchronization
P531: Phase deviation limit for activation of synchronizing error
message
P532: Frequency control range of the synchronizing controller
output
♦ Switch on the operating and synchronizing converters and wait for
them to accelerate to reference frequency.
