5 FUNCTIONS
The SI-C card is a communications interface card for operations, adjustments, and monitoring using the PLC program
with the Varispeed Series as a remote device station for the CC-Link. Both bit data and word data cyclic transmissions
are available, and high-speed communications up to 10 Mbps are possible.
5.1 Initial Settings
Set the following parameters whenever necessary, before starting communications between the Inverter and the PLC.
It is particularly important to check the settings to parameters b1-01, b1-02, and F6-06.
Parameter Name Description Default F7 G7
b1-01 Reference selection *1
Sets the input source of the frequency reference.
0: Digital Operator
1: Control circuit terminals (analog inputs)
2: Memobus Communications
3: Option Card
4: Pulse Train Input
1 Y Y
b1-02 Operation method selection *1
Sets the source of the run command input.
0: Digital Operator
1: Control circuit terminals (sequence inputs)
2: Memobus communications
3: Option Card
1 Y Y
F6-01
Operation Selection when
Communication Error is
Detected
Selects the Stop Method when a comm. error is
detected (BUS).
0: Deceleration to stop (by the time set to C1-02)
1: Coast to stop
2: Fast stop (using the deceleration time set to C1-09)
3: Continue running *2
1 Y Y
F6-02
Input Level of External Fault
from Communication Option
0: Always detect
1: Detect during operation
0 Y Y
F6-03
Operation during
Communication Option
External Fault Input
0: Deceleration to stop
1: Coast to stop
2: Fast Stop.
3: Continue running *2
1 Y Y
F6-06
Torque Reference / Torque
Limit Selection from
Communication Cards *3 *4
0: Torque reference/limit from comm. disabled
1: Torque reference/limit from comm. enabled
1 N Y
*1 Set b1-02 to 3 to run/stop through the CC-Link communications. Set b1-01 to 3 to specify the frequency.
*2 Selecting "Continuous Operation" will allow the operation with the Inverter to continue when a fault occurs.
Provide other measures such as an emergency stop switch for safe operation.
*3 Enabled when A1-02 (Control Mode Selection) is set to 3 (flux vector control) or 4 (open loop vector 2).
In this case, the d5-01 (Torque control selection) setting can be used to select the torque reference or the torque limit.
d5-01 = 0 (Speed control): Torque limit setting
d5-01 = 1 (Torque control): Torque reference value
*4 When F9-06 is set to 1 (default), the motor may rotate unless the torque reference or the torque limit is set from the PLC.
