Description
V/f CL-V/f OLV CLV AOLV
Sets the MFAO terminal FM output signal level.
0 : 0-10V (Lower Limit at 0)
1 : -10 to +10V (Bipolar Reference)
V/f CL-V/f OLV CLV AOLV
Sets the MFAO terminal AM output signal level.
0 : 0-10V (Lower Limit at 0)
1 : -10 to +10V (Bipolar Reference)
V/f CL-V/f OLV CLV AOLV
Sets the level at 10 V when U1-08 [Output Power] is set for analog output.
Description
V/f CL-V/f OLV CLV AOLV
Sets the communication slave address for drives.
Note:
• Re-energize the drive or set H5-20 = 1 [Communication Parameters Reload =
Reload Now] after you change the parameter setting.
• Setting 0 will not let the drive respond to MEMOBUS/Modbus communications.
V/f CL-V/f OLV CLV AOLV
Sets the communications speed for MEMOBUS/Modbus communications.
Note:
Re-energize the drive or set H5-20 = 1 [Communication Parameters Reload =
Reload Now] after you change the parameter setting.
0 : 1200 bps
1 : 2400 bps
2 : 4800 bps
3 : 9600 bps
4 : 19.2 kbps
5 : 38.4 kbps
6 : 57.6 kbps
7 : 76.8 kbps
8 : 115.2 kbps
V/f CL-V/f OLV CLV AOLV
Sets the communications parity used for MEMOBUS/Modbus communications.
Note:
Re-energize the drive or set H5-20 = 1 [Communication Parameters Reload =
Reload Now] after you change the parameter setting.
0 : No parity
1 : Even parity
2 : Odd parity
V/f CL-V/f OLV CLV AOLV
Sets the motor Stopping Method when the drive detects CE [MEMOBUS/Modbus
Communication Err] issues.
0 : Ramp to Stop
1 : Coast to Stop
2 : Fast Stop (Use C1-09)
3 : Alarm Only
V/f CL-V/f OLV CLV AOLV
Sets the function that detects CE [Modbus Communication Error] issues during
MEMOBUS/Modbus communications.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the time to wait to send a response message after the drive receives a command
message from the master.
Note:
Restart the drive after changing the parameter setting.
V/f CL-V/f OLV CLV AOLV
Sets the detection time for CE [Modbus Communication Error] issues when
communication stops.
V/f CL-V/f OLV CLV AOLV
Sets the unit of measure used for the MEMOBUS/Modbus communications monitor
register 0025H (output voltage reference monitor).
0 : 0.1 V units
1 : 1 V units
