Start-up, synchronization (SIMOVERT VC)

Prerequisites
Start-up steps
4-2
♦ The converter output terminals (U2/T1, V2/T2, W2/T3) of the
operating- and synchronizing converters are connected up.
♦ The standard converter start-up has been completed.
♦ Switch-off 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 wiring
recommendations, Table 2 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.
♦ Switch on the power supply with the front panels closed.
♦ Parameterize the hardware configuration for the operating- and
synchronizing converter corresponding to the slot of the TSY. For
slot 2 (right): P90 = 4; for slot 3 (center): P91 = 4 (refer to the
Instruction Manual of the SIMOVERT MASTERDRIVES (Section 4
"Start-up", Expert application and Section 5 "Parameter List").
♦ For the operating and synchronizing converters set the V/F open-
loop control mode for textile applications (P163 = 2, refer to the
Instruction Manual of the SIMOVERT MASTERDRIVES (Section 4
"Start-up", Expert application").
♦ Parameterize the binary inputs and outputs on the TSY board of the
synchronizing converter corresponding to the wiring above (refer to
Table 2 and the instruction Manual of the SIMOVERT
MASTERDRIVES (Section 4 "Start-up", and Section 5 "Parameter
List").
♦ Parameterize the same characteristics, direction of rotation and
frequency setpoint for the operating and synchronizing converters
(refer to the Instruction Manual of the SIMOVERT MASTERDRIVES
(Section 4 "Start-up", V/f open-loop control for textile applications).
The maximum synchronizing converter frequency should be
selected to be approximately 1 Hz greater than that of the operating
converter.
