TOSHIBA

Parameter Explanations (cont'd)

Item 146, DC INJECTION STARTING FREQUENCY - Use this parameter to set the frequency at which

DC injection begins. DC injection can be initiated remotely by programming one of the input terminals appropriately (see Items 44-54 and page 9-9).

Item 147, DC INJECTION CURRENT - sets the current level to be employed during DC injection. Amount can be in % of drive rating or in amps (set by Item 296).

Item 148, DC INJECTION TIME - sets the number of seconds DC is applied to the motor.

Drive will DC inject approximately 60% FLA continuously, 80% for 100 seconds, and 100% for 2 seconds without an INVERTER OVERLOAD trip.

DC injection is active when the drive's output frequency is below DC INJECTION START FREQUENCY and the drive has a STOP command or a zero reference. DC injection is also active when the drive's output frequency is below Item 32, END FREQUENCY.

Item 149, FWD/REV DC INJECTION PRIORITY CONTROL - When drive is running in forward

direction and is given a reverse reference, this parameter determines whether or not DC injection is active between DC INJECTION STARTING FREQUENCY and 0 Hz. Also, a setting of "1" gives DC injection priority over a new run command. With a setting of "0", a new run command has priority over DC injection.

Item 150, MOTOR SHAFT STATIONARY CONTROL - This parameter enables a continuous DC injection into a stopped motor. Amps are set by DC INJECTION CURRENT / 2. Motor shaft stationary control starts after DC injection and continues until "ST"-"CC" is opened, power is turned off, drive emergency stops, or parameter is changed.

Item 151, EMERGENCY STOP SELECTION - This parameter determines ESTOP method.

Item 152, EMERGENCY OFF DC INJECTION TIME - This is an unique DC injection time for ESTOPs.

Item 153, NUMBER OF RETRY ATTEMPTS - The H3 can be programmed to restart after a fault occurs. This parameter sets the number of retry attempts. Speed search is automatically on during retry. Retry will

not function if Item 172, FAULT TRIP EEPROM SAVE ENABLE is on.

Item 154, TIME BETWEEN RETRY ATTEMPTS - Adjust this parameter to set the number of seconds between retry attempts.

Make sure that workers are not exposed to danger from CAUTION equipment suddenly re-starting when a fault occurs and

a retry selection option other than "0" has been selected.

Item 155, REGENERATION POWER RIDE THROUGH CONTROL - H3 models 2080-2110 and 4080-4270 take control power from the DC bus; enabling this function allows use of regeneration energy from the motor to maintain control during a brown-out. Accel/decel times may need to be adjusted to avoid overvolltage trips. Always confirm operation.

Item 156, REGENERATION POWER RIDE THROUGH TIME - Use this parameter to limit the ride- through time (effective only if there is sufficient regen energy).

Item 157, AUTO-RESTART (MOTOR SPEED SEARCH) - This parameter enables the drive's ability to catch a spinning motor:

0:Speed search off

1:Drive performs speed search after a power glitch

2:Drive performs speed search after "ST"-"CC" is made

3:Both 1 and 2 above

A drive with a forward direction command will catch a reversing motor.
