EN-18 Param- eter Num- ber Name Description V/f Pattern Settings E1-01 Input voltage setting This setting is used as a reference value for protection functions. E1-04 Max. output frequency (FMAX) Output Voltage (V) Frequency (Hz) To set V/f characteristics in a straight line, set the same values for E1-07 and E1-09. In this case, the setting for E1-08 will be disregarded. Always ensure that the four frequen- cies are set in the following order: E1-04 (FMAX) ≥ E1-06 (FA) > E1-07 (FB) ≥ E1-09 (FMIN) E1-05 Max. output voltage (VMAX) E1-06 Base fre- quency (FA) E1-13 Base Voltage (VBASE) Motor Data Settings E2-01 Motor rated current Sets the motor data.
Set the correct values if the thermal motor protection is used. E2-03 Motor no-load current E2-05 Motor line-to- line resistance Digital I/O Settings H1-01 to H1-05 Terminal S3 to S7 function selection Refer to page 20, Digital Input Func- tion Selections (H1-01 to H1-05) for a list of selections H2-01 and H2-02 Terminal M1- M2 and M3- M4 function selection Refer to page 20, Digital Output Func- tion Selections for a list of selections Analog I/O Settings H3-08 Analog input A2 signal level selection Selects the signal level input at multi- function analog input A2. 0:0 to +10V (11 bit). 2:4 to 20 mA (9-bit input).
3:0 to 20 mA (9-bit input) Ensure to switch S1-2 to “V” before using a voltage input. H3-09 Analog input A2 function selection. Selects the multi-function analog input function for terminal A2. H3-13 Terminal A1/ A2 switching Selects on which terminal the main frequency reference can be input. 0:Use analog input 1 on terminal A1 for main frequency reference. 1:Use analog input 2 on terminal A2 for main frequency reference. H4-01 Terminal FM monitor selec- tion Sets the number of the monitor item to be output (U1-) at terminal FM/ AM. H4-04 Terminal AM monitor selec- tion H4-05 Terminal AM gain Sets the analog output AM gain.
Sets the percentage of the monitor value that is equal to 10V output at terminal AM. Param- eter Num- ber Name Description Motor Protection 0:Disabled 1:General-purpose motor protection (fan cooled motor) 2:Inverter motor protection (externally Motor protec- cooled motor) L1-01 tion selection 3:Vector motor protection When the Inverter power supply is turned off, the thermal value is reset, so even if it is enabled, pro- tection may not be effective. Power Loss Ride Through 0:Disabled (DC bus undervoltage L2-01 Momentary power loss detection (UV1) detection) 1:Enabled (Restarted when the power returns within the time set in L2-02.
When L2-02 is exceeded, DC bus undervoltage is detected.) 2:Enabled while CPU is operating. (Restarts when power returns dur- ing control operations. Does not detect DC bus undervoltage.) Stall Prevention L3-01 Stall preven- tion selection during accel 0:Disabled (Acceleration as set. With a heavy load, the motor may stall.) 1:Enabled (Acceleration stopped when L3-02 level is exceeded. Acceleration starts again when the current has fallen below the stall prevention level). 2:Intelligent acceleration mode (Using the L3-02 level as a basis, accelera- tion is automatically adjusted.
Set acceleration time is disregarded.) L3-02 Stall preven- tion level dur- ing accel Effective when L3-01 is set to 1 or 2. Set as a percentage of Inverter rated current. L3-04 Stall preven- tion selection during decel 0:Disabled (Deceleration as set. If deceleration time is too short, a DC bus overvoltage may result.) 1:Enabled (Deceleration is stopped when the DC bus voltage exceeds the stall prevention level. Deceleration restarts when the voltage falls below the stall prevention level again.) 2:Intelligent deceleration mode (Deceleration rate is automatically adjusted so that the Inverter can decelerate in the shortest possible time.
The set deceleration time is disregarded.) When a braking option (Braking Unit) is used, always set to 0. L3-05 Stall preven- tion selection during running 0:Disabled (Runs as set. With a heavy load, the motor may stall.) 1:Deceleration using deceleration time 1 (C1-02.) 2:Deceleration using deceleration time 2 (C1-04.) L3-06 Stall preven- tion level dur- ing running Effective when L3-05 is 1 or 2. Set as a percentage of the Inverter rated current. Fault Restart
