Note: 1) Control equipment code
"T" -KT□Cam controller (asymmetrical resistance)
"K-KT□ cam controller (asymmetric resistance, one-phase open-circuit start of the rotor)
"Y" or "P" -PQR1, PQR3, PQR5, PQY1-6Y, QY1-6Y, PQK6401, etc. pan control panel (cabinet)
"S" or "St"-XQS single-phase braking type lifting control box: (five-stage resistance four-stage switching, six-stage resistance five-stage switching)
"Z" or "Ze"-XQZ type grab control box: (four-segment resistance and three-segment switching. Five-segment resistance and four-segment switching)
"Q"-XQR10 type is XQD6402 type lifting control box: (seven-segment resistance and six-segment switching)
"F"-QR2S two-stage reverse connection brake lift control box: (Note: The number of poles of the motor model is added with the word "J" for seven-segment resistance and six-segment switching.)
2) Power-on duration rate: "1"-15%; "2"-25%; "4"-40%; "6"-60%;
