P712 (CB parameter 2)
Function switch
With this parameter, different options and functions can be activated. At the
moment three switches are implemented:
•
HOLD / CLR:
If communication on CC-Link breaks down. The set value will be hold or
cleared and the motor will still run or immediately stop. For more
information about reaction to a communication breakdown refer to chapter
4.10 "Fault reaction on communication errors" and to documentation of
converter (e.g. P722 and P692).
•
SPEED / TORQUE CONTROL
You can select control of motor speed (frequency) or torque.
•
DIAGNOSTIC DATA OF CC-LINK OR PKW
For diagnostic purposes parameter r732 displays different CBL data; only
for diagnostic (refer to chapter 6.3 "Evaluation of the CBL diagnostic
parameter")
Default value of P712 is 0.
P712
Reserved Bit 2 Bit 1 Bit 0
Bit 0 = 0 hold function on communication breakdown
1 clr function on communication breakdown
Bit 1 = 0 speed control of the motor
1 torque control
Bit 2 = 0 diagnostic data r732.14 ... r732.25:
CC-Link data (Master
⇒
CBL; CBL
⇒
Master)
1 diagnostic data r732.14 ... r732.25:
parameter data PKW request / reply (CBL <-> CU)
Example
P712 = 5: => Bit 0 = 1; Bit 1 = 0; Bit 2 = 1;
CBL handles the data for regulation of motor speed (frequency). At a break
down of communication the motor stops (CLR-function of bit 0). The
diagnostic area r732.14 ... r732.25 shows the data structures of PKW request
and PKW reply at communication between CBL and CU; refer to Fig. 4-7
(chapter "Handling PKW via CC-Link") and chapter 6.3 "Evaluation of the CBL
diagnostic parameter".
