Standard ● 1 high-speed pulse output terminal (open-collector) for a square-wave signal output in the frequency range 0 to 100 kHz ● 1 digital output (DO) terminal ● 1 relay output terminal ● 1 analog output (AO) terminal that supports either a current output in the range 0 to 20 mA or a voltage output in the range 0 to 10 V. Expanded capacity: ● 1 extra DO terminal ● 1 extra relay output terminal ● 1 extra AO terminal that supports either a current output in the range 0 to 20 mA or a voltage output in the range 0 to 10 V. |
■ De-rating
The drive can be operated at above rated ambient temperature, altitude and default carrier frequency by de-rating drive capacity.
When carrier frequency of the drive is increased above default setting, you need to de-rate rated drive output current according to the following table:

Drive operation between -10°C to 40°C is normal without de-rating. Operation between 40°C and 50°C requires output current de-rating. Rated output current must be de-rated for 1.5% per 1°C temperature rise. Permissible maximum temperature is 50°C.
(3) Altitude De-rating
The drive must be de-rated for an installation altitude of above 1000 meters because cooling effect available from ambient air reduces. Rated output current must bede-rated for 1% per 100 meters. Maximum altitude is 3000 meters.
