Stall Prevention (Current Limit) Level while Running (n094)
Sets the stall prevention (current limit) level while running in units of 1%. (Inverter rated current = 100%) Factory setting: 160% A setting of 200% disables stall prevention (current limit) while running. If the stall prevention action current at speed agreement exceeds the value set for n094 for longer than 100 ms, deceleration starts. If the output current exceeds the value set for n094, deceleration continues. If the output current goes to the value set for n094, acceleration to the set frequency starts. Stall prevention acceleration/deceleration settings during operation are set either for the currently selected Acceleration Time, i.e., for Acceleration Time 1 (n019) and Deceleration Time 1 (n020), or for Acceleration Time 2 (n021) and Deceleration Time 2 (n022).

Note: When the analog signal (0 to 10 V) input into terminal FR is used as the motor overheat signal for the PTC thermistor input (FR) (when n141 is set to 1 or higher), the signal cannot be used as a frequency reference or for PID feedback. (There are restrictions when setting constants.) The following settings cannot be set from the Digital Operator. (After the error is displayed on the Digital Operator, the value returns to the value before the change.) If the following settings are set from the MEMOBUS, a constant setting error will occur. (oP7 will flash on the Digital Operator.)
When n141 is set to 1 or higher: n004 (Frequency Reference Selection) cannot be set to 2, 3, or 4 (frequency reference of 0 to 10 V, 4 to 20 mA, or 0 to 20 mA, respectively). When n128 (PID Control Selection) is set to a value other than 0 (with PID control), n164 (PID Feedback Value Selection) cannot be set to 0, 1, or 2 (feedback values of 0 to 10 V, 4 to 20 mA, or 0 to 20 mA, respectively). Constant n141 cannot be set to 1 when n004 is set to 2, 3, or 4, and n128 is set to 1 and n164 is set to 0,1, or 2. Terminal Connection Diagram of PTC Thermistor Input Motor Overheat Protection

Selecting Cooling Fan Operation
In order to increase the life of the cooling fan, the fan can be set to operate only when Inverter is running n039 = 0 (Factory setting): Operates only when Inverter is running (Continues operation for 1 minute after Inverter is stopped.) =1: Operates with power ON.
Using MEMOBUS (MODBUS) Communications
Serial communication is available with V7AZ using a programmable controller (MEMOCON series) and MEMOBUS (MODBUS). Refer to the MEMOBUS Instruction Manual (Manual No.: TOEZ-C736-70.1) for details of communications.
MEMOBUS (MODBUS) Communications
The MEMOBUS system is composed of a single master (PLC) and slaves (1 to 31 V7AZ units). Communication between master and slave (serial communication) is controlled according to the master program with the master initiating communication and the slave responding. The master sends a signal to one slave at a time. Each slave has a preregistered address number, and the master specifies the number and conducts signal communications. The slave receives the communications to carry out designated functions and reply to the master.
CAUTION While the constant is being stored after an Enter Com-
mand was issued, response to the commands or data input with the keys on the Digital Operator (JVOP-140) becomes poor. Be sure to take some measures for an emergency stop by using the external terminals (setting the external terminal to Run Command priority, or setting the multi-function input terminal to external fault, External Baseblock or emergency stop).
Maximum number of writing times of the non-volatile memory used for V7AZ is 100,000; do not execute the Enter Command excessively.
When a constant is changed from the Digital Operator, the constant data on the RAM is written to the non-volatile memory without the Enter Command. Constant No. n170 Name Enter Command operation selection (MEMOBUS communications) Unit Setting Factory Range Setting 0, 1 0
n170 Setting Description Accepts the Enter Command (constant saving) while the Inverter is stopped. Always accepts the Enter Command (constant storing). The new constant becomes valid even if the Enter Command is not input. If the Enter Command is not used, however, the value returns to the stored value when the power supply is turned ON again.
Register number 0900H is used only for write-in. If this register is readout, a register number error (error code: 02H) occurs.
Error Code 01H Function code error Function code from PLC is other than 03H, 08H, or 10H. Improper register number 02H No register numbers to be accessed have been registered.

6 Programming Features Performing Self-test
V7AZ is provided with a function to perform self-diagnosis for operation check of the serial communication I/F circuit. This function is called self-test. In the self-test, connect the sending terminal with the receiving terminal in the communication section. It checks if the data received by V7AZ is not being changed. It also checks if the data can be received normally. Carry out the self-test in the following procedure. 1. Turn ON the V7AZ power supply. Set constant n056 to 35 (selftest). 2. Turn OFF the V7AZ power supply. 3. Make the following wiring with the power supply turned OFF. 4. Turn the power ON.
