IDN 33 (S-0-0033) Secondary Operation Mode 1
Defines the drive's operational mode when the AT status word bit 9 is clear and bit 8 is set. The master requests a particular operation mode through the MDT control word (bits 8 and 9). The master can switch between the operation modes defined within this IDN and the mode defined within the primary operation mode ( IDN 32 ) with these bits in real time. Switch into position control during fast moving, could result a jerk.
The following table may be used to define the secondary operation mode 1. All reserved bits are not supported and must be zero. The gain for bit 3 is defined by IDN 296 , Velocity Feed Forward Gain. It is not possible to select position control with motor feedback in IDN 32 and position control using external feedback in IDN 33, also the reverse setting of this IDNs is not possible and will be checked by the drive (refer to IDN 117 ). For position control with external feedback 2, all position data, e.g. also IDN 51 , are used for the external feedback.
