1 When 1kW and 1.5kW amps are used with single phase power input, the continuous power rating must be derated to 70%. Reference speed/torque curves for the selected motor for de-ratings.
2 Use the amplifier within the ambient temperature range. When enclosed, the temperatures inside the cabinet must not exceed the specified range.
3 Regarding: “DB (Dynamic Brake) OFF Function”.

  • (1) The dynamic brake function is always ON when the main power is not applied.
    (2) The dynamic brake function is always ON when the logic control power is not applied.
    (3) The dynamic brake state during SVOFF can be selected with SWI-1 (ON or OFF).
    (4) When SVOFF or an alarm state occurs during move, the dynamic braking function can be enabled or disabled by the state of DBOFF input signal at the CNI connector.

WARNING! If the DB is disabled, the load will coast free.
