(35) Energy-saving coefficient reduction ratio (Cn-59)
• In order to prevent over excitation in the low frequency area, this constant reduces
output voltage at low frequency. Set the reduction ratio at 6Hz. Output voltage is reduced
by the reduction ratio (Cn-59) when output frequency is 6Hz or obtained by linear interpolation
between 6 and 15Hz as shown in the figure below.
Please refer to Appendix A for a detailed discussion of Energy-Savings Mode.
(36) Motor code (Cn-60)
• By setting this code, energy-savings coefficient is set to Cn-58 when a TECO motor is
used. This motor code is the same as that used for motor constant setting (Sn-01). By setting the
capacity and initializing by Sn-01, the same code is written to Cn-60. Therefore, when the AC drive
and motor have the same capacity, this setting is not needed. When an exclusive use motor or
some other manufacturer’s motor is used and its motor constant is not known, or when the
AC drive and motor have different capacities, set the motor code corresponding to the motor
voltage and capacity to Cn-60. The motor codes are shown in the table below.
